I like the idea of tool containers, but I don't understand how to resize them. The padding margins are massive, I'd like to make them much smaller.
Also, when working near the top of the designer canvas, tool container often stray too high, see pic. I can't grab these boxes to bring them back onto the canvas, because the only grabbable toolbar is off the top of my canvas. How can I bring these tool containers back into play I wonder?
