diff: 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 open a discussion on [GitHub feedback](https://github.com/github/feedback/discussions) or email [GitHub support](https://support.github.com/contact) about doing it.
