A very nice update, Michael!

As per usual new features spawn new items on the wishlist:-) Here are two:
The new features of the filleting tool are great, how about an option to select a custom profile curve? (so that the fillet works similarly to Sweep)
The new Units feature is propably very nice for those who need it, it would be even better if the changes were reflected in the viewport grid. (Inches and feet would have thicker lines for every 6 and 12 units instead of every 5 and 10, the cm display would subdivide to mm when zoomed far enough in etc.)
