UltraMouse

UltraMouse adds a pop-up menu to the click of your middle mouse button, allowing you to quickly accomplish a choice of eight different tasks. UltraMouse saves you time and reduces computer related strain. No longer will you have to look and navigate to those minimize/restore/close buttons, you will have already performed the action instinctively.

There any many built-in functions to choose from, such as switch task or to make any window always on top. Alternatively any menu item can be customized to simulate a key-stroke combination or to launch an application. You can also set program-specific actions for different applications. Even more tasks can be performed using the mouse gestures- which require just a simple motion of the mouse.
