all GUI bjectes have operator += implemented, it's easy to concolude there should be an -= operator implemented as well, which isn't. one should just search to find removeChild. and for the GUI class it get's worse since there is no removeChild method to begin with (if i'm not wrong I have to call Gui->desktop()->removeChild(X) to remove some object from GUI)

Agreed. I've wondered the same thing.

Makes sense. I'll add this

Cool, thanks!
