[Issue 1] Transition duration input seems to be bugged, or limited to integers.
Still, it works if you copy/paste the value from another field.
Later edit:
[Issue 2] Pull requests do not work on my side. I get the following error:
Pull request command failed. This is the stderr output:
Error creating pull request: Forbidden (HTTP 403)
It seems that this one is related to github permissions somehow.
