We've gotten a lot of feedback from users that it's hard to differentiate multiple codespaces in the same repo, especially if they're on the same branch. To make it a little easier to tell codespaces apart, we've started automatically creating "friendly" (and fun) names for your codespaces.
If you don't like our names, we're also working on the ability for users to re-name their codespaces.
For more information on Codespaces, see "GitHub Codespaces overview".
