On the desktop app, I find that when I get a panel filling half of a window (now with a "+" on the other side), it is difficult to get rid of that blank area. If I want to have the panel fill the entire window I have a hard time grabbing the frame so that I can drag it across. Is there a hotkey or some other way to have that panel fill the entire window without grabbing the one-pixel wide frame? Is there some trick that I'm missing? Or can someone make the frame two pixels wide?
