LiteSwitch X is an application switcher for OS X. Instead of using c-tab to switch apps in the Dock, use it
(or another keyboard combo) to activate LiteSwitch X. Once activated, the program allows you to apply a number of actions to any open application. These actions can be applied via contextual menus or keyboard shortcuts.
The switching window’s colours, transparency, position, and size are all easy to customize, and you use the program to control how windows behave when switching applications (in other words, hide all, hide current, and so forth).
