Hi!

Again, thanks for the extensive contribution!

(Please also see my review of the engine part.)

Here, I'd like to disable it entirely for lightning infill. In my tests, it didn't change anything, and this feature doesn't make a lot of sense in that case, since that type of infill is already meant to address these issues on its own.

(I'm less inclined to want to change it for gradual infills steps, as it works, and makes a little more sense.)

For the rest, it seems to work quite nicely! I did run into something I think is at the very least a bit counterintuitive if I multiply the # of infill lines (see the pictures). I don't think this can do much harm, but OTOH, I don't think those lines are needed there.

(how it is with this feature off, for comparison):
