AltSnap vs Dexpot

AltSnap has no write-up on Specifiction yet; its figures are above.

Dexpot adds switchable virtual workspaces to Windows, so you can organize windows, files, and shortcuts across separate desktops. Switch desktops with a keyboard or mouse. A full-screen preview gives a live view of desktops and lets you drag windows between them; the window catalog tiles the windows on one desktop and opens the preview when you drag a window. Desktops can have their own files, shortcuts, wallpaper, and background color, including different backgrounds on each monitor. Rules can act on new windows that meet a condition, for example by keeping them on top, minimizing them to the system tray, or changing their transparency. Included plugins add hot corners, mouse-wheel switching, a taskbar overview, grid navigation, 3D transitions, wallpaper clocks, and desktop slideshows. Dexpot has a programming interface for plugins and third-party programs, and a Plugin SDK 1.5. The maker says its components work with multiple monitors, which can be excluded from desktop switching. Private use is free; the pricing note lists paid plans from €24.90 and a 30-day trial. The listed download is version 1.6.14 Build 2439 for Windows XP, Vista, 7, 8, and 8.1, including x64 and server versions.
