I am constantly dragging graph editor window in order to widen so much needed viewing space, it is not very convenient process. I am working on a big monitor and using scaling on windows 200% so there is a little space. Why such feature still not exist? I have switched from Unity3d to Unreal Engine recently and there you can just fullscreen any selected window ( this feature was made many years ago). At least say how difficult it is to implement, please!?
