AW: [Feature Request] Fenstergröße
This is actually more of an issue with the Unity3D Game Engine than anything else. Generally a proper resolution change requires a restart. A lot of games just hide this fact by restarting a "sub scene" of the overall application therefore making it "look" like it doesn't restart.
Basically its possible... it's just a lot of work for very little return right now. Most players I'm sure would prefer we got other things working first. Don't worry though. It is in the requests list.
