I’ll take a look at FredoCorner.
Not sure what you mean by stretching out the geometry. An example of what I’m doing–the vertical edge near the cursor was done in a previous session. But, I now want to round two edges. So, I need to make that vertical corner square again, so I can pick that edge AND the horizontal edge before doing the rounding.
On a related issue–it seems the geometry associated with the round corners somehow gets confused by layers.
When I hide the “top” layer, the rounded corners disappear. So, I thought maybe I accidentally had the top layer as active when I did the rounding.
But, when I hide the “dock” layer, the rounded edges disappear with the rest of the geometry on the dock layer. That would seem to indicate the corners are on the dock layer.
