Is there any way to hide a control when editing a xib in Xcode 4?

I have a nib in my Mac app that includes a few image views. Theese images make me difficult to edit the controls layered behind them or even check their position. I know I can check the Hidden property and make them semitransparent but I'd prefer just hide th开发者_C百科em momentarily (from the IB, not in runtime) as I do when work in any design program.

Is there any way to do this?. Am I missing something?.
