Hey there, I looked at this but still have no idea what it does. You say it helps limit the number of open PRs and encourages closing them and issues, but there is nothing telling me how it does it unless you read the entire screenshot which is more than I want to do at a glance to figure out what it does.
It seems to me that it auto closes the PRs that someone tries to open if the PR threshold is met? Does it do that to issues too? I think I wouldn't want a limit on issues personally.
I like the idea of the tool though!
