Has anyone thought about printing narrower lines in order to get sharper corners? Once Linear advance or Pressure advance is activated, you don't get bulging corners anymore... but can we do better?

Has this been implemented anywhere yet? Does it have a name?

So you would need different later heights around the edges just to stack those ever thinner lines? How do you think this will interact with the rest of the print?

This shows what happens with two different extrusion rates at the same layer height.

That's a really lovely illustration

I would keep the layer height constant.

The lines are not circular. You can have narrow lines and wide lines with the same height. The height is controlled by the space between the nozzle and layer below. The width is controlled by the amount of material you extrude.

I get that but your original sketch seemed to be showing smaller and smaller radiuses shaping the edge, which necessarily implies thinner and thinner layers. Now I fail to see what's different from what sliders currently do.
