I'm curious as to whether you are dogfooding Projects, especially when feature work spans multiple repos. If so a "how Github uses Projects" tutorial may be worth considering.

Indeed, many teams are - the original iteration of Projects was released to staff a few months ago (as is common with many of our product releases), so we're continuing to learn how teams are using it most effectively. Yesterday's release to the public will help with that effort too.

I personally use it on my team at the moment - it's been pretty useful and we've passed along frequent feedback to the platform team responsible for it.
