I use and like the GitHub staring auto bookmark feature, however I’m a bit tied on the tagging with the programming language feature. There’s two reasons I star GitHub projects:

1. I embed this project into my own projects, it’s a library or framework or something along those lines. Tagging these with the programming language is useful, as obviously if I’m working in python I only want python libs.
2. I’m a user of the project but am unlikely to ever contribute to it nor embed it into my own stuff - its entirely standalone. An example would be borg, the backup program for example - I run it, but I’m never going to put it in my code.

When I’m searching for stuff that matches #1, currently it’s polluted by things in #2.
