Obviously this raises the requirement for a 'colour' parameter we can expose to the material too. 3 x Sliders is a little painful :D

Yeah its all working OK, my actual issue was that if you have a field selected so for instance you clicked in a vector1 field to edit the number and then try and delete the node 'whilst still editing the number' you can't delete the node but on reflection that seems fair enough :)

Hmm, yes it does seem to be working now.. this only happened to me during an extended session with it. I am using a different mac now, I'll check it on my laptop again later

Once again, this would be nice if its optional

Yeah it would be good to be able to config that, just because the most common way of panning in Unity is MMB and dragging a box around nodes to select and move really is an almost unconscious action and so keeps surprising me when the canvas pans.

Certainly fixed the connection problem. the curves are very low fidelity in bezier - is this intentional?

:( not really sure how to help I'm afraid, obviously will keep testing it anyway. If you like you could perhaps share the code you use of the lines and I can show that to one of the guys here

Just want to chip in same problem for me on mac 4.3 and mac 4.2 sorry no access to Windows right now..
