Yes, I thought about including it in the WME Tool, but maybe you're right and it's easier to use an existing general tool.
I don't know WinCVS, but I'll check it out soon. My problem is, that I'm working with a friend on a project and it would be good to synch via Internet. The above descriptions(click in windows explorer etc) make me think, that WinCVS might not have that functionality. Maybe it has.
Other suggestions related to the IDE are Syntax checking(ok, I can use the JavaScript Setup for Ultraedit), automatic syntax-"guessing" (like I enter "actor." and the IDE tells me all the methods/attributes of that class, see eclipse or other IDEs) and debugging of single scipts, without starting the whole game. I think these things would need an included Text(Script-)editor in ProjectMan.
