Hi everyone,
I’m observing some strange behavior with the “Tune Length of a Single Track” feature.
Details are shown in the video.

So it’s already been two months since this critical bug became known, but the developers don’t seem to care — they’re busy working on version 10. Why am I not surprised, once again. It feels like KiCad is used purely for hobby projects — as long as you can draw something, that’s good enough…

That’s an incredibly insulting, derogatory, and inflamatory assertion to make against primarily volunteer developers. Perhaps it’s a rather tricky bug to track down?

If you look at the commit logs for the past two months, the vast majority are bug-fixes, with a small proportion being v10 features / improvements. (Some hit both categories - bug fix and improvements for v10).

A fix has now been commited for this, which will be in 9.0.3.
