for example, a Python category at the top and unrelated projects (to each other) but common to Python are nested under Python in separate repos under Python ? does Github have something like ‘Groups’ in Gitlab ?
I’m afraid GitHub has a completely flat repository structure at the moment. You can potentially add topics to your repositories to classify them, and search via topic to see similar repositories grouped together, but I appreciate that’s not really what you’re after!
We’re always working to improve GitHub, and we consider every suggestion we receive, so perhaps you’d like to submit a feature request through our official product feedback form so that our product team can see exactly how you’d like the organization of repos on GitHub to work?
