A Chrome extension for hiding the useless parts of GitHub UI.

Removes the Copilot prompt, changelog, and Home / Feed navigation.

Hides unused tabs and links upstream repositories to your fork.

Adds direct links to your open and closed pull requests beside the repository tab.

Hides top-level entries on hover. Restore them from the eyes menu. The list persists per fork network.
