I nowhere said that i hate or dislike GM as a software anyway
But it's hard to like GM's room editor and overall interface, that's what i've written generally. In the YoYo forums even the staff admitted that everything needs a revamp but i also read that they couldn't update it because GM:Studio was heavily based on GM8 and changing them would have caused problems. Indeed GM's scripting language (GML) and its script editor are one of the few things in the program that are very good (i use GM8's interface in Studio because the icons of the green Studio scheme look, well, pretty terrible).
But it's pointless to talk about it, since it's said that GM2.0 will be a total revrite so, hopefully, a lot of things will be changes.
