I got two little suggestions in terms of a faster drawing-workflow.
1) Could be nice to make a copy of a form while holding down “alt” and use arrows to make a copy - just like in adobe apps.
2) Would be nice to have the „break off node“-function in context-menu.
(And in this case I had an idea: customizable context-menu? F.e. in the phase of drawing I need other contexts than in hinting.) An alternative could be to use something like “alt”-“click” to break a node.
