It looks like I will have the fillet curve as requested above, in the next beta. It will work slightly differently than he shows though - you can select a single curve (made up of multiple segments with sharp corners), then do Fillet, and then points will display at the corners and you can select which points you wish to fillet or push done to do them all. Then those corners will get filleted by the radius that you choose.

More comments on other stuff tomorrow...
