Regarding the inside corners, I think the idea behind having rounded corner paths is to avoid too much material in the corner (towards the outline of the corner). Be aware that we are looking at center lines of the extrusion, not at outlines. If we assume the extrusion footprint to be a perfect circle around every point along this center line, then the theoretical outline (i.e., one of the envelopes of all the circles) actually still forms a perfect corner even if the center line in the corner is round, unless the radius of the center line in the corner is bigger than half of the extrusion width. And indeed, it seems that the radius of the round corner in your screenshot is actually half of the extrusion width.
I am just not so sure whether the whole idea is such a good one. How do other slicers go around inside corners? And how does it look like in actual prints in comparison to KISSlicer?
