There are thousands of issues on drupal.org. Core and the common modules have loads of issues on their own. And a lot of them are not easily understandable, well written or are simply forgotten about.
To make it easier for everybody we can provide an easy workflow and standards to clean up those issues. This grease monkey provides you an array of big buttons and preset text you can rely on.
If not you will have to download / clone the project and call the Issue_Helper.user.js from your local filesystem.
My Opinion and Experience
I started to work on the issue queues of views and i18n. They are so incredibly large you basically can't maintain them anymore. I quickly figured that I should start digging in the oldest issues and that there are so many you can just close straight away. Especially support issues.
