Rado, Excellent!!! This is really, really nice and a *huge* step forward. This looks usable in its current state, even though I know there's lots more to think about with regards to plugging it in properly. And I'll be interested to see what Pat LeSmithe could add. Thanks for your hard work on this.
The only limitation I'm seeing, that wasn't advertised, is that I can't "drop" a vertex outside of the editor canvas, or outside of the frame with the scrollbar. So effectively, I can't remove a vertex. But maybe with a restart it might behave - I've got a few other weird things going on at the moment in my browser. Anyway, I'll experiment some more in the next couple of days and report back if this behavior persists.
