Configurable mouse actions in present windows for clicking a window and desktop.

It's possible to activate a window, exit without activating, bring window to current desktop, send window on all desktops, mimize the window and close the window.
Clicking desktop allows to activate selected window, exit without activating, show the desktop (minimize all apps) and of course do nothing.
