Thanks a lot. It applies nicely now!

First feedback: It would be great to make the corner radius variable
instead of fixing it to 25% of the shorter pad edge and <=0.25mm. [1]

This other tool I use allows to adjust the radius of the corners
for each pad. So Kicad would not be able to import a design without
cheating or tweaking these footprints.

My fp-generator starts currently with r_min=0.1mm for the tiny stuff
and then uses fixed increments of r_delta=0.05mm depending on the
shorter pad edge to avoid having many different apertures ending
up in the gerber output... But basically, any corner radius would
be allowed.

Greets,

Clemens
