Small suggestion: re-sizeable popup windows.

A bit self explanatory. Mostly for the "Open map from..." window, where you choose the map in the wad that you want to edit. If the map name is longer than 6 characters, you can't see the map's full name, which makes it harder to find the map you actually want to edit. (In this case, I'm working on the ZDoomWars map pack, and the map names are ZDWARS1 - ZDWARS23, which just shows up as 'ZDWARS..')

I just want it to be re-sizeable so I can expand it horizontally to maybe see the map's full name. Might prove useful to others as well.
