Most importantly it doesn&#x27;t have raise-on-click, which allows you to actually use overlapping windows, because who has infinite screen space? Now you can use overlapping windows drag and drop actually works, can&#x27;t drop if the window you just dragged from now covers it. So there&#x27;s drag and drop load and save, no save-as boxes.<p>Secondly window moving&#x2F;resizing, 1. windows aren&#x27;t full screen, 2. you can drag the title bar with the 3rd mouse button to keep the z-order the same. 3. if you try to drag to resize off the side of the screen, the window moves in the opposite direction so it still gets bigger. 4. 3rd button click on a scroll arrow goes in the opposite direction, 3rd button drag on a scroll bar allows 2d movement.<p>Thirdly: No menu bars, everything is a pop up menu, an infinitely large Fitts target. Also you can 3rd button click on a menu to keep it open so you can select another menu option.<p>Fourthly: The taskbar shows applications, not windows, to open a new document you click the taskbar icon. Drag to taskbar icon opens file in that application, drag to a window on that application inserts&#x2F;merges&#x2F;etc. Application level tasks on on the taskbar menu, quit, preferences. Document level tasks are in the document menu.<p>Obviously this requires application support, can&#x27;t do it with just an X11 window manager. <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ROX_Desktop" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ROX_Desktop</a> uses some of the ideas, although the project seems dead.
