Built-in top bar for windowed mode

On the Mac especially, I don’t think it looks very appealing having the default OS X bar at the top when not in full screen. Would be nice to have a built-in true top bar that matches whatever theme I select.

I don’t see it as something hard to implement considering that when in full screen it is actually there.

Just a little design improvement I think would be great, as I personally like to work in windowed mode.
