Noobish question:
How do we get to close a window?
Let's say I have 2 maps opened, but I finished worked with one and I want to close it. How do I do so? :S

EDIT: And is there a way to have Triggers/Data/Terrain/etc. layers all open in the same window?

I believe you can go to File->Close and that will close your current project window.

As for the second question, I don't think so (with my fidgeting with the editor anyway). And those are actually what Blizzard calls "modules".

Oh great, it worked! =D
I was pressing "Close window" ;o
Thank you! =)
