Might conflict with some user customizations (e.g. what if they make 
another window selected right after some of these commands?) or mouse 
clicks (you click in another window, the handler quits the current 
window and resizes it so that your click is not within the current 
window's box, creating an ambiguous situation).

Could work, but sounds like a significant change.
