I wish to see in Allegro 5 ability to perform simple operations on windows: maximize, minimize, restore (back from maximization/minimization), hide and show.
Motivation (quote from forum):
"Another usage is 'boss mode', feature that you can encounter in some of casual games. Pressing a special key cause game to hide, so boss will not blame you for playing at work time. ;) From my point of view this is funny feature (annoying if you are the boss), but some customers like it."
