52) This is a pretty important one:
More Fullscreen Options. Right now, if I set the layout to be 720p and my monitor doesn't natively support that resolution, Construct just resizes and stretches the whole screen with complete disregard for the aspect ratio - which makes the game look much less flattering in fullscreen mode.
Also, I think I caught a bug with fullscreen: With a color overlay that has a layer effect applied to it and the canvas object on top of everything that has a the sharpen shader applied to it, if I go to fullscreen, the screen fills up with artifacts.
And one problem I always had is still pretty annoying: If I start the runtime, go to fullscreen and quit the game, the IDE crashes.
In general, that stuff should really get looked into - being able to switch to fullscreen without any hick-ups is really important and being able to retain the aspect ratio of the project is also vital.
