In a game where you have many different sprites in orders it becomes frustrating to have to right click, click on order, and then click on "to front". There is a shortcut for "bring forward" but then you have to hold cntrl+up for about three seconds which become tedious when you have lots of sprites to deal with. I would suggest a shortcut like cntrl+alt+up for "to front" and cntrl+alt+down for "to back".
PS: Ctrnl+y for redo would also be a useful shortcut.
