I have a dual monitor and I wish I can pop out the \"source pane\"(where I edit my code), so that I can edit the code in one monitor and track everything else in another.
I'm using the latest Studio and encountered similar needs. I found that ctrl+shift+number will suit my needs most of the time since it zooms to the pane that I desire and can also back to the full four window layout.
An additional trick is customize the hotkey to alt+number [1,2,3,4,5] so the pane zooms more handy with one click by your left hand on the keyboard.
Hope it helps.
