My request for UV

1. To add "Clear seams". Very annoying green seams that appear until you don't press Edit Seams. Is it for the automatic Unwrap/Unfold? How disable it?

2. On pressing Esc - don't to close UV Map tool,  but finish editing seam(instead double click). It is need to discuss.

3. if you get the chance, instead of manual selection of polygons, to provide automatically, as is done in 3dcoat (watch the video). But it is probably not easy to do.

I'm selecting polygons, make a seams. Press Unfold and NVil offer me to select Color for island (in 3d viewport). These polygons are painted in this color.
