## Background
FIELD
This invention relates generally to visual desktops for computer systems, more particularly to systems and methods for a journal page for applications executing on computer systems.
DESCRIPTION OF THE RELATED ART
A Web browser (“browser) is a software program running at a client computer system that displays web pages from the Internet. The browser displays the information by interpreting the markup language (e.g., Hypertext Markup Language, HTML; Wireless Markup Language, WML; Extensible Markup Language, XML; Standard Generalized Markup Language, SGML, etc.) used to build home pages on the Web. The coding in a markup language file tells the browser how to display the text, graphics, links and multimedia files on the home page. If the browser itself is unable to display the file, the browser may utilize a plug-in, such as a multimedia player or audio player, to present the file to the user. The browser also interprets HTML tags within the HTML document as links to other web sites, or to Web resources, such as graphics, multimedia files, news groups, or files to download.
Using the browser, a user may visit a large number of web sites in various browser sessions. At each web site, a user may also visit multiple web pages during an individual browser session. In some cases, a description and an address (e.g., the Uniform Resource Locator or URL) for a web page visited during a browser session may be saved in a sequential, stack-based “history” list, possibly allowing a user to return to a previously visited web page by selecting its description from the history list. A user can open the history list to select previously viewed resources, which are usually identified by the title or address of the web page. A user can also “bookmark” a currently viewed web page in a Favorites list to facilitate selection of the bookmarked resource from the Favorites list for a later visit.
Browsers can also be used to traverse a file system, and a history list can be used to return to a previously visited directory or file within the file system. Generally, browsers may be said to browse resources, whether on the Web, in a file system, or in some other type of data storage.
As users use browsers during these browse sessions, a user can accumulate a greater number of pages in the history list. It can become difficult to find a previously web page since the pages are identified by their respective URLs. This may force a user to guess which page from the history list is the preferred web page. Alternatively, a user may go to the initial page of a web site of the preferred page and recreate the path to the preferred page. This process of relocating a preferred page on a website via their respective URLs is inefficient and time consuming.
Accordingly, there is a need in the art for a mechanism for users to quickly locate recently viewed websites and/or files without recreating the conditions for a search or browsing.

DETAILED DESCRIPTION OF EMBODIMENTS
For simplicity and illustrative purposes, the principles of the present invention are described by referring mainly to exemplary embodiments thereof. However, one of ordinary skill in the art would readily recognize that the same principles are equally applicable to, and can be implemented in, all types computer systems, and that any such variations do not depart from the true spirit and scope of the present invention. Moreover, in the following detailed description, references are made to the accompanying figures, which illustrate specific embodiments. Electrical, mechanical, logical and structural changes may be made to the embodiments without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense and the scope of the present invention is defined by the appended claims and their equivalents.
Embodiments relate generally to systems and method for filtering module for local and third party searching. More particularly, a filter module can be configured to filter the history of a browser. The filter module can apply heuristic algorithms to generate a filter list. The filter list can then be applied to the browser history in order to remove less useful URLs from the browser history. For instance, as a browser traverses a web site, there can be intermediary pages that are necessary but are not the preferred page by the user. These intermediary pages clutter the file history. As a result, a user may not be able to locate the preferred page again after an elapse of time and additional browsing. With the filter module, the browser history can become more of a high level journal as the intermediary pages are filtered out. Accordingly, the user can then be assured that the history list contains preferred pages. As a result, the user can efficiently and with minimal effort return to a previous web page.
