Added a Wireframe option for the channel that you are translating to. This is one of the ugliest hacks I have ever done - and it is ugly. Only draws 2-out-of-3 lines per triangle, so some edges are missing, and some lines are doubled-up.
But it should give you a good idea of the UV coords. I find it useful for quickly browsing the channels to find the ones that I'm looking for. It's also useful for whipping out wires in a hurry (at current doc size) so you don't have to mess with external wire renders.
It is ugly and in no way compares to vector (of course).

Been working on getting my wiki cleaned up a bit and should be adding an MCH repository one of these days.
