F6 one thing I forgot to mention, I have an annoying issue with the drop down window in Round corners, its squashed up.

very nice tool, works on SU6
doesnt do groups so you need to group edit or explode

and you only get one chance for offset input. Get it wrong and you must revert to sharp edge start - obvious really, no big deal

think of the time spent doing it manually YUK

thanx mille foix
