GitHub Canned Responses v1.0.9resigned1
Sometimes you've made mistakes and you have to triage 700 GitHub issues and Pull Requests. A lot of them will need the same answer, and your wrists will start hurting from all the switch-to-edit-copy-pasting. This extension helps with that.
The extension adds a little "canned response" button inside the comment editing view, that allows you to filter through existing canned responses and add them to the comment. It comes with a few default canned responses, but you can edit them and add your own!
