As the name suggests, this will complement the existing Github Desktop to implement a dark theme. Did this on some spare time and because the interface was too bright to use at night.
Copy the lines from the uiaddon.css above to the bottom of your ui.css file. DO NOT OVERWRITE ANY LINE THAT WAS ORIGINALLY IN THE FILE.
For Windows, the ui.css file can be found in %localappdata%\GitHubDesktop\app-<version number>\resources
