As part of our “Give Orbit some love for Helios” initiative I started adding categories to Orbit repositories. Whenever you include an Orbit p2 repository in your target platform, you’ll now be able to cherry pick only the bundles you really need from a convenient set of categories. No need to download any unnecessary overhead.

Try it out yourself. Here is a link to an Orbit p2 repository with categories:

I also captured a  screenshot for your convenience:

Frankly, I’m not a creative guy but I had to come up with some categories. Your feedback on the categories is really appreciated.
