A browser extension that makes GitHub cleaner & more powerful

Refined GitHub Browser extension that simplifies the GitHub interface and adds useful features
We use GitHub a lot and notice many annoyances we’d like to fix. So here be dragons.
Our hope is that GitHub will notice and implement some of these much needed improvements. So if you like any of these improvements, please email GitHub support about doing it.
GitHub Enterprise is also supported. More info in the options.
