If you are looking for a fast alternative, we're building www.kitemaker.co (I'm one of the founders). We're part of the upcoming YC batch, and I'd be happy to help you onboard and import existing projects if needed.
I think this article is a pretty good description of good pm. I’ve both been pm myself and managed teams og pms, and anyone fitting this description would be a great hire.
Happy to answer questions about the issue screen! :)
To foster collaboration, we made the description huge (you can write anything from a line to 1 pager, to X pagers there). We also believe that communication contains persistent information and non-persistent information, so we have on the same screen an activity feed with comments (for non-persistent information), next to the description (for jotting down persistent information).
We also have a principle of hiding complexity, so there are not 15 fields to fill in for each issue, a title is enough.
