CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation of U.S. application Ser. No. 13/247,924, filed on Sep. 28, 2011, which in turn is a continuation of U.S. application Ser. No. 13/094,489 filed on Apr. 26, 2011, issued as U.S. Pat. No. 8,713,473 on Apr. 29, 2014, the disclosures of which are hereby incorporated by reference in their entireties herein. 
     
    
     FIELD 
       [0002]    The disclosure relates to, among others, operating systems, software applications and user interface devices, and, more particularly, as examples without limitation, to methods and apparatus for processing application windows. 
       BACKGROUND 
       [0003]    A web browser is commonly used with computational devices, such as laptops, smartphones, tablet computing devices, personal digital assistants (PDAs), etc. Web browsers continue to grow in popularity as a tool used to access a particular web page, and perform related features. It is common for a user&#39;s homepage to include customized user settings, such as a default web page, and other sources of information. For example, customized web pages may include local weather, email, text messaging, horoscopes, video plug-ins, backgrounds, etc. 
         [0004]    Currently, web browsers use a tab metaphor to represent a browser context presently running within the browser. A web browser may have multiple browser contexts running at any given time. Any of the browser contexts may be selected for display via their respective tabs. Each tab is associated with a corresponding uniform resource locator (URL) field that includes a web address. Also, some additional tools or buttons may be present allowing the user to navigate backward and forward between the various browser contexts. Each tab can be selected at any time providing the user with the option to switch to a different browser context. 
         [0005]    On mobile devices, the tab metaphor cannot be used to represent browsing contexts because the screen real estate is not large enough. Within the display area of a mobile device, tabs would occupy a large portion of the screen and would not scale very well horizontally as the number of tabs increases. Tabs would also be more difficult to select given the imprecision inherent to small screen touch-based user interfaces. 
       SUMMARY 
       [0006]    In one or more example embodiments, an apparatus may include one or more memories and one or more processors.

     DETAILED DESCRIPTION 
       [0016]    Embodiments described herein refer to illustrations for particular applications. It should be understood that the invention is not limited to the embodiments. Those skilled in the art with access to the teachings provided herein will recognize additional modifications, applications, and embodiments within the scope thereof and additional fields in which the invention would be of significant utility. 
         [0017]    In the detailed description of embodiments that follows, references to “one embodiment”, “an embodiment”, “an example embodiment”, etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. 
         [0018]    Example embodiments may provide a way to visualize and switch between several browser contexts currently displayed on a mobile device. The browser contexts may be optimized for touch-based mobile devices that are equipped with a small screen. Example embodiments provide a way for users to have multiple browser contexts displayed on a mobile device having a relatively small display screen. Each browser context is represented by a frame that encloses the browser context. The frame may include a web page viewable to the user. Frames may overlap freely, allowing users to select which browser context they would like to view or interact with at any given time. 
         [0019]      FIG. 1A  is an illustration of a hand held user computational device displaying a set of browser contexts, according to an embodiment. Referring to  FIG. 1A , a handheld mobile device  101 , such as a cellular phone, mobile station, smartphone or other handheld computational device is shown. The handheld device  101  includes a display area  103 , which the user may view and control via a touch screen sensor configuration overlaid on the display area  103 . A user hand silhouette  105 A is illustrated as controlling the viewable content of the display area  103 . For example, the user may be viewing one browser context and may select a switcher icon  135  to change the view from one browser context to multiple browser contexts. In this example, by selecting the switcher icon  135 , the user&#39;s view switched from one browser context (not shown) to the current view of frames  109 ,  111 ,  113  and  115 . Additional frames  117 ,  119 ,  121 ,  123 , and  125  are stacked at the bottom of the page. Each of the plurality of frames may be open and running within the context of an operating system of the mobile device  101 . 
         [0020]    In operation, the user may select a browser application and launch a browser context. The initial browser context may be opened and viewable as a homepage linked to the browser. The user may navigate to a particular web address and download a web page of interest. Upon selecting a web page, the user may desire to open additional browser contexts to view additional web pages without closing or navigating away from the previously accessed web page. As multiple browser contexts are opened, a queue or list of browser contexts may be displayed by a group of frames  109 ,  111 ,  113 ,  115 ,  117 ,  119 ,  121 ,  123 , and  125 . Frame  109  may include a first webpage “www.webpageA.com” of a first browser context, and additional webpages “www.webpageB.com”, “www.webpageC.com”, “www.webpageD.com”, “www.webpageE.com” “www.webpageF.com” “www.webpageG.com” “www.webpageH.com” and “www.webpageI.com” may be displayed in additional frames  111 ,  113 ,  115 ,  117 ,  119 ,  121 ,  123 , and  125 , respectively. 
         [0021]    The order of the frames  109 ,  111 ,  113 ,  115 ,  117 ,  119 ,  121 ,  123 , and  125  may be dictated by the order of accessing the webpages via the browser application. For example, the user may launch a browser application and access a first webpage, then minimize or move the current view of that webpage via its browser context in order to launch additional browser contexts. Switching views may be performed by selecting the switcher icon  135 . This procedure may be performed multiple times to launch numerous different browser contexts and corresponding frames containing web pages. As the number of frames continues to increase, the display may only provide a maximum number of viewable frames at any given time. In the present view of  FIG. 1A , only four frames  109 ,  111 ,  113 , and  115  are displayed at a time. The other frames,  117 ,  119 ,  121 ,  123  and  125  are stacked at the bottom of the display area  103 . The number of frames viewable per display may vary. However, the display screen real estate is limited to only a finite number of frames. 
         [0022]      FIG. 1B  is an illustration of a hand held user computational device displaying another set of browser contexts, according to an example embodiment. Referring to  FIG. 1B , the user may perform a scrolling operation by scrolling upward from the bottom of the screen, as indicated by the arrow  129 , additional frames not previously illustrated may effectively scroll into the viewing area of the display area  103  due to the user&#39;s scrolling movement. For example, frames  117 ,  119 , and  121  are additional frames containing different browser contexts that may not have been visible prior to the user&#39;s hand movement scrolling upward as indicated by the user&#39;s hand position  105 B. The user hand movement  105 B scrolling upward caused the additional frames  117 ,  119 , and  121  to be visible, while stacking frames  109 ,  11 , and  113  at the top of the screen. Frame  115  from  FIG. 1A  is still visible at the bottom of the display area  103 . Frames  123  and  125  remain stacked at the bottom. Additional user hand movements may cause browser contexts to be removed or added. For example, a downward scrolling, or by touching a particular browser context and moving to the right, as indicated by arrow  127 , may cause the manipulated browser context to be permanently removed from the list of available browser contexts included in the display area  103 . The user can continue to scroll upward with the movement  105 B as shown in  FIG. 1C  and frame  115  is then stacked at the top with frames  109 ,  11 , and  113 . Frame  123  is now visible in display area  103 , and frame  125  remains stacked at the bottom of the display area. 
         [0023]    As indicated above, browser contexts may include a web page. Referring again to  FIG. 1B , a toolbar at the top of the display screen  103  may include a switcher icon  135 . The switcher icon  135  may operate to turn on the page switcher mode. When the switcher icon  135  is selected, the current page size may be slightly reduced as if the visible area zoomed out by approximately 10-15%. This modification to the area reveals a frame for each web page. Each frame features the corresponding web page title, a favicon illustration indicative of the logo or certain content of the web page (not shown) and an option to close the frame and its corresponding contents. A favicon can also be referred to as a shortcut icon, a website icon, a URL icon, or a bookmark icon. The favicon is a file containing one or more small icon associated with a particular webpage or website. 
         [0024]    Other frames and their corresponding web pages are overlapped over or under the current web page frame. The present view of the display  103  may include from 1 to N web pages, the layout divides the available vertical space evenly between web pages. Beyond N pages, the layout decreases the visible area for each web page progressively, starting from the current page. Such a display configuration may be derived from a display algorithm. For example, the spacing available for each web page is determined by the formula: (HeightOfTotalArea−padding)/(NumberOfPages*ScaleAmount). The “HeightOfTotalArea” is the total area available for viewing in the display area  103 , the “padding” is the distance between each frame, the “NumberOfPages” is the total number of browser contexts open and the “ScaleAmount” is a scaling variable that is inversely proportional to the total number of browser contexts open. For example, the larger the number of browser contexts open, the smaller the scale amount will be to accommodate each of the browser contexts as a percentage of the total display area height. 
         [0025]    The spacing may also be capped to a minimum amount (e.g., 230 pixels) to ensure that there is always enough of the page visible for other purposes. On the top and bottom of the screen, the user can view a stack of pages. Touching the stack automatically expands the stack from the top or bottom. For example, if a user touched the stack in  FIG. 1A  at the bottom where frames  117 ,  119 ,  121 ,  123 , and  125  are stacked, the frames expand from the bottom upward with frames  119 ,  121 ,  123 , and  125  visible and frames  109 ,  111 ,  113 ,  115 , and  117  stacked at the top of the display area. Touching the stack at the bottom would expand the frames upward until no more frames were left at the bottom of the display area. The same is true if the use movement was touching the stack at the top of the screen. Then the frames expand from the top downward. For example if the user touched the stack in  FIG. 1C  at the top where frames  109 ,  113 ,  113 , and  115  are stacked, then the stack opens downward and frames  109 ,  113 ,  113 , and  115  are displayed with frames  117 ,  119 ,  121 ,  123 , and  125  stacked at the bottom. Touching the stack at the top would expand the frames downward until no more frames were left at the top of the display area. 
         [0026]    An example formula used for stacking browser context frames at the top of the screen is discussed below. Frames may move freely and linearly up to a certain degree. Thereafter, the frames begin to decelerate using a dampening curve, such as ((y/2)+0.5)̂2 which is multiplied to its linear vertical position. This is bounded at the top by a constant value. Users can control the frame overlapping feature to navigate to the frame that contains their desired browser context. For example, each frame can be moved by sliding the frame by touching the screen. In the switcher  125 , pressing the switcher button selects the page that was previously visible. This allows users to easily and naturally identify web pages included in browser context frames, since they are only slightly smaller 10% to 15% than normal and are still readable. 
         [0027]    While overlapping frames may obscure some web page contents, web sites are generally designed to have some strong brand identity at the top of the page. This allows an optimized view to be displayed at the top of each web page at almost full size. As noted above, the constant “N” may be currently set to a value, such as 2, 3 or 4 on mobile phones. Examples discussed above are described in portrait mode but modifications may also be adapted to display content in landscape mode with frames ordered horizontally.
