From October 1st, 2013 to April 13th, 2016, 33% user give 5-star rating, 33% user give 3-star rating, 33% user give 1-star rating. for Trello to GitHub Issue chrome extension.
This would be an awesome tool, but judging by the github repo it's deprecated. Keep getting 'auth error', and the related github issue seems to imply it's dead :(
Didn't try it because it requires access to: Code Pull requests Wikis Settings Webhooks and services Deploy keys ... If you change it to just need authorisation for Issues, that'd be great!
Very useful in my workflow
