JackyBoy: That must just be you - I've had Retain Component Spacing on for over a year now and I've only ever set the option once :) Firebert: Yeah, you could probably script it quite easily to store the UV pivot across edits. Maybe I'll give it a spin this weekend.
to add to kodde and MoP, once you have reset your pivot, you can only use that pivot per use, per transform tool. so lets say you snap your move pivot to the top left UV, then switch to your Scale tool, the Scale tool will reset to the center of your selection instead of staying at the same pivot location as your Move…
