On the contrary, I think there was lots of progress; there's lots of
useful feedback from the initial design proposal I posted. I am a bit
sad to admit that I'm not working on it at the moment as I had
originally planned, though, because other priorities slipped in and I am
not able to work on this for a while. Therefore if someone else wants
to work on this topic, be my guest -- otherwise I hope to get on it in a
few months.

Agreed, and I don't think just hiding the stitches is good enough.
