IceWM 4.0.0 brings alt+tab improvements

IceWM, the venerable X11 window manager, has released a new version, bumping the version number to 4.0.0. This release brings a big update to the alt+tab feature.

The Alt+Tab window switcher can now handle large numbers of application windows in both horizontal and in vertical mode. Type the first letter of an application class name in Alt+Tab, to select the next instance window of that application class. Select an application by pressing one of the number keys. Select an application by mouse in Alt+Tab in horizontal mode. Support navigating the quick switch with all navigation keys. Press the menu button on Alt+Tab to open the system menu. QuickSwitchPreview is a new mode to preview applications. These previews are updated while the quick switch is active.
