The keyboard command for full screen in the system is ⌃⌘F. Why are we changing that?
Also the full screen implementation needs work. The edit window covers the whole screen. I can’t write with the text spanning the whole screen. It should be a smaller window. There has to be a larger margin on the left and the right. Would be better if this was customizable.
If you have a window in Bike in regular mode, you are making sure that the window is of the comfortable width. In full screen mode, the window might be the same size. Full screen mode spanning the whole width of the screen is not useful to me.
