mini task? shape distribution
by Mark Proctor
In the RuleFlow we have shape alignment, which is something I added a
little while back, we don't have shape distribution - i.e. controlling
the vertical and horizontal spacing between shapes, like in visio.
Anyone want to take this task on? Would add a nice bit of polish to the IDE.
