Is there a way to hide the titlebar in an NSWindow? I don't want to have to completely write a new custom window. I can't use NSBorderlessWindowMask because I have a bottom bar on my window, and using NSBorderlessWindowMask makes that disappear. I also tried using setContentBorderThickness:forEdge: with NSMaxYEdge and setting it to 0, that didn't work either.
Any help is appreciated
