<<Yeah that is probably one of the biggest remaining "gotcha" type things in MoI right now where construction curves can interfere with selecting edges.

I have some ideas on how to improve this - one of which is now in the v2 beta where you can look over there to know if the selected object is a curve or edge, but there are also some other things that I can probably do to help out additionally when I get a chance to work on it in the future.>>

Is it possible to have curves highlight in a different color than solids/surfaces?
