========================= Documentation: http://wiki.blender.org/index.php/User:Psy-Fi/UV_Tools Major features include: *16 bit image support in viewport *Subsurf aware unwrapping *Smart Stitch(snap/rotate islands, preview, middlepoint/endpoint stitching) *Seams from islands tool (marks seams and sharp, depending on settings) *Uv Sculpting(Grab/Pinch/Rotate) All tools are complete apart from stitching that is considered stable but with an extra edge mode under development(will be in soc-2011-onion-uv-tools).
