Oh now that you mention it, a sharable link would be a must. This would promote curated "Awesome..." repos/links.
It would be ideal if it were part of the fediverse naming convention. For example "/m/multi-subreddit-name/c/group1@domain1/c/group2@domain2/..."
It would allow full transparency, the ability to update / change it... places could even provide URL shorteners for it.
Edit 2: formatting (come'on Lemmy don't let me down)
Oh, I hope this (eventually) works with Skyrim VR!
