KiPadCheck GitHub for nightly 406 has been updated.
You can now select min/max drill size (which are measured against the drill set),
select the drill set from a few different metric and imperial choices,
modify units just by entering them in the boxes,
and modify the debug layer (where object outlines are written if you select debug mode).
Data entry overall is pretty tedious because you have to enter everything by hand every time you open the dialog for the first time in a session. I’ll be adding load/save to a file soon.
