The requirement of a description.txt for add-ons is effectively restricting SpeedKart Maps, some deathmatch maps that do not have descriptions, and other potential gamemode maps from being put into Glass.
Also I would love being able to do more stuff while uploading an addon. Add dependencies, screenshots, etc without waiting for it to be approved. Also the limit on add-on title length (which errors out instead of showing an actual warning) is pretty small. Would love to make my titles longer.
I love what you guys are doing with Glass so far in any case, but I hope you make it easier for mod makers to do what they want.
