Just saw this - recently released FREEBIE script bundle (although I think most were also released individually prior to this), some of which are bound to be very helpful to quite a lot of us, so thanks to 3Dart.it and script author Khanh Trieu for making them available...

Highlights for me are the Global SDS switch , Edit Optimize, Null Alignment tools and the Object Manager sorting ones.
Selection to Circle also included; alas that cannot acknowledge surface curvature, but still useful in some circumstances if you don't have a better one...
They say 'free', but it's donation-ware really - so I'd encourage people to help them out with a contribution if these are really useful to you...
Enjoy.
