Question: What user interface used by Apple is compared to the RK Launcher?

full_context: Document 1: Filelight: Filelight is a KDE graphical disk usage analyzer, part of the KDE Utils package, which uses the sunburst chart technique to display disk usage. Instead of showing a tree view of the files within a partition or directory, or even a columns-represent-directories view like "xdiskusage", it shows a series of concentric pie charts representing the various directories within the requested partition or directory and the amount of space they use (this method being known as a sunburst chart, ring chart, or multilevel pie chart). A user may also click on the pie chart segment representing a particular directory, and repeat the analysis for that directory, right click that segment to open a file manager or terminal emulator in that location, or copy to clipboard or delete the directory, and they may right click the segment representing a file to open it, copy it to the clipboard, or delete it.
Document 2: Launchpad (macOS): Launchpad is an application launcher for macOS developed by Apple Inc., introduced in Mac OS X Lion. A labeled icon represents each application listed in Launchpad. The user starts an application by single-clicking its icon. Launchpad's graphical user interface provides an alternative way to start applications in macOS, compared with other options such as the Dock (toolbar launcher), Finder (file manager), or Spotlight (desktop search).
Document 3: Aqua (user interface): Aqua is the graphical user interface (GUI) and visual theme of Apple's macOS operating system. It was originally based around the theme of water, with droplet-like components and a liberal use of reflection effects and translucency. Its goal is to "incorporate color, depth, translucence, and complex textures into a visually appealing interface" in macOS applications. At its introduction, Steve Jobs noted that "one of the design goals was when you saw it you wanted to lick it".
Document 4: Apple Help Viewer: Help Viewer is a WebKit based HTML viewer for Mac OS X aimed at displaying help files and other documentation. It is found in /System/Library/CoreServices/Help Viewer.app. The default file extension is ".help". Help index files are generated with Help Indexer. Mac OS X applications typically use Help Viewer to display their help content, rather than a custom system.
Document 5: Macintosh: The Macintosh ( ; (branded as Mac since 1998) is a series of personal computers (PCs) designed, developed, and marketed by Apple Inc. Steve Jobs introduced the original Macintosh computer on January 24, 1984. This was the company's first mass-market personal computer featuring an integral graphical user interface and mouse. This first model was later renamed to "Macintosh 128k" for uniqueness amongst a populous family of subsequently updated models which are also based on Apple's same proprietary architecture. Since 1998, Apple has largely phased out the Macintosh name in favor of "Mac", and the product family has been nicknamed "Mac" or "the Mac" since the development of the first model.
Document 6: Classic Mac OS: The "Classic" Mac OS is a graphical user interface-based operating system developed by Apple Inc. for its Macintosh family of personal computers from 1984 until 2001, the original member of the series of Macintosh operating systems. The Macintosh platform, which was introduced in the classic Mac OS, is credited with having popularized the early GUI concept. Mac OS was preinstalled on every Macintosh computer that was made during the era it was developed; it was also sold separately in retail stores.
Document 7: Zedge: Zedge is a mobile content discovery platform and community where users can download content to customize their smartphones and other mobile devices. The app includes wallpapers, ringtones, alert tones, app icon customization, which is currently in its beta form, and which is only available for Android phones, and games on the Android, iOS and Windows Phone platforms. Zedge has more than 170 million installs Android and iOS. The app uses a recommendation engine that analyzes anonymized user data in order to create smart suggestions for wallpaper, ringtone, and game downloads. IDT Corp. is majority investor in Zedge Holdings, the app's parent company.
Document 8: Bluebottle OS: Bluebottle (formerly known as AOS and now as A2) is a modular, object-oriented Operating System with unconventional features. It has automatic and garbage collected memory management and provides soft real-time features and is developed at ETH Zurich. It is the next generation Native Oberon, the Oberon operating system for bare PC hardware. It is small and fast and supports multiprocessor computers. It is completely based on an upward-compatible dialect of the Oberon programming language called Active Oberon. Its user interface supports a "point-and-click" metaphor to execute commands from text, similar to clicking hyperlinks in a browser. The interface is a zooming user interface. More and detailed information can be found in the Russian wikipedia article about A2 (operating system).
Document 9: Organic user interface: In human–computer interaction, an organic user interface (OUI) is defined as a user interface with a non-flat display. After Engelbart and Sutherland's graphical user interface (GUI), which was based on the cathode ray tube (CRT), and Kay and Weiser's ubiquitous computing, which is based on the flat panel liquid-crystal display (LCD), OUI represents the third wave of display interaction paradigms, pertaining to multi-shaped and flexible displays. In an OUI, the display surface is always the locus of interaction, and may actively or passively change shape upon analog (i.e., as close to non-quantized as possible) inputs. These inputs are provided through direct physical gestures, rather than through indirect point-and-click control. Note that the term "Organic" in OUI was derived from organic architecture, referring to the adoption of natural form to design a better fit with human ecology. The term also alludes to the use of organic electronics for this purpose.
Document 10: Macintosh operating systems: The family of Macintosh operating systems developed by Apple Inc. includes the graphical user interface-based operating systems it has designed for use with its Macintosh series of personal computers since 1984, as well as the related system software it once created for compatible third-party systems.
Document 11: FlickRocket: FlickRocket FlickRocket is a cloud based e-commerce platform with a focus on secure distribution of digital content. Content owners can set up custom webshop front ends or use it to deliver DRM protected digital content for 3rd party web shops.
Document 12: RK Launcher: RK Launcher is a free application, similar to the dock in the AquaGUI Or Mac OS X. The application has support for themes and can support docklets made for ObjectDock and Y'z Dock. Icons with the file extension .PNG and .ICO can be placed on the dock for shortcuts to applications and documents. The application also mimics the smooth zooming and scrolling effects of the Mac OS X smooth zooming animations, as well as the effects used when minimizing windows (Aladdin's Lamp Effect).
Document 13: MacOS version history: The history of macOS, Apple's current Mac operating system originally named Mac OS X until 2012 and then OS X until 2016, began with the company's project to replace its "classic" Mac OS. That system, up to and including its final release Mac OS 9, was a direct descendant of the operating system Apple had used in its Macintosh computers since their introduction in 1984. However, the current macOS is a Unix operating system built on technology that had been developed at NeXT from the 1980s until Apple purchased the company in early 1997.
Document 14: Files (Apple): Files is a file management app developed by Apple Inc. for devices that run iOS 11. Discovered as a placeholder title in the App Store just prior to the company's 2017 Worldwide Developers Conference, the app was officially announced at the conference shortly thereafter. Files allows users to browse local files stored on their device, as well as files stored in cloud storage services, including iCloud, Dropbox, Google Drive, and OneDrive. It allows for the saving, opening and organization of files, including placement into structured folders and sub-folders. iPads running iOS 11 will be able to drag-and-drop files between Files and other apps, while iPhone users will be limited to drag-and-drop inside Files itself. Further organization can be done through the use of color-coded or custom-named tags, and a persistent search bar allows for finding files inside folders, though not inside other apps. A list view enables different sorting options. The app offers the exclusive playback of high-quality FLAC audio files, and also offers support for viewing text files, images, "Music Memos", and Zip archives, as well as limited support for video.
Document 15: MacOS: macOS (pronounced ; previously Mac OS X and later OS X) is the current series of Unix-based graphical operating systems developed and marketed by Apple Inc. designed to run on Apple's Macintosh computers ("Macs"). It has been preinstalled on all Macs since 2002. Within the market of desktop, laptop and home computers, and by web usage, it is the second most widely used desktop OS after Microsoft Windows.
