I bet this is far down the priority list right now, but it would be a great help for using the curve tool if it could snap to surfaces and/or vertices, like when moving objects normally in Unity.

Small detail that would make it easier for the artists to use for placing wires and fences and such.

Have you tried using the Project Curves to Colliders button in the CURVES section? If you have colliders added to the list, it should project the curve points.

Oh wow, no, sorry about that! I was just trying with the same hotkeys as Unity uses.
I'll remember to check next time..
