This one is a gem. Have you ever wanted a simpler GitHub interface with some additional features? Your wish has been granted.
Some notable improvements:
- Mark issues and pull requests as unread
- Reaction avatars showing who reacted to a comment
- Clickable references to issues and pull requests
- The option to wait for checks when merging a PR
In general you can expect less clutter, some UI improvements and more shortcuts. The cool part is that GitHub has implemented many of the features that were originally introduced by this extension.
