So indispensable, I always forget what functions are part of it and not core Blender.

Very useful

Great tool. So helpful in so many cases.

Very useful for modeling, can't imagne living withdout it, easy 5 star.

works properly

Sometimes I get unexpected results creating a face

Oldie but goodie, essential for modelling and retopology

Was better in previous versions

Together with LoopTools this is an essential modeling plugin.
