* Mouse support:
* - bring a window on top if you click on its taskbar
* - click on the top-bar of the active window and drag+drop to move a window
* - click on a window to bring it to focus
* - allow scrolling in tree/textview on wheel-scroll event
* - click to activate button or select a row in tree
* wishlist:
* - have a little [X] on the windows, and clicking it will close that window.
