Give it buttons? Are you mad? You can't clutter an editor with crap like graphics, fancy buttons, pretty menues and worthess garbage. All professional software avoids this (except Metacreations, a perfect example of how NOT to make an interface). 3DS Max, Maya, Softimage, Lightwave.. No fancy buttons, just straight to the point. As an editor should be, the more effeciency the better. Learning is irrelevant, if you aren't smart enough to learn it, chances are you aren't smart enough to make a decent map anyway. :P
