Is there a way to customize toolbar in Xcode 4? Reorder buttons, remove default and add new? Also I want to turn off text under toolbar buttons, since I run Xcode 4 on 13" Macbook where every pixel is precious.
To turn off text underneath the buttons just cmd+click on the top right button (on the level with the traffic lights). This is a global thing.
The rest you're stuck with I'm afraid.
