SuperSwitcher Alternatives
SuperSwitcher is described as '(more feature-ful) replacement for the Alt-Tab window switching behavior and Ctrl-Alt-Left/Right/Up/Down workspace switching behavior that is currently provided by Metacity' and is an app in the os & utilities category. There are eight alternatives to SuperSwitcher for Windows, Linux, BSD, Xfce and Mac. The best alternative is Alt-Tab Terminator. It's not free, so if you're looking for a free alternative, you could try VistaSwitcher or Skippy-XD. Other great apps like SuperSwitcher are Mission Control, HyperKeys, SmartTab and Alt-Tab Thingy.
Alt-Tab Terminator is a powerful task management utility for Windows. It replaces the Alt-Tab with a box that shows a list of all tasks, their names and preview snapshots, and enables to take actions on them. It is the successor to VistaSwitcher.
