I talked with one of the devs, and we discovered a problem with this idea. When looking at your own library, you see unlisted ones as well, so your most recent one may be #10, or which 7 are public and 3 are unlisted, say.
If you tried to share a URL that included say #5, it would land on a different synth for somebody who could only see your public ones. So, it wouldn't be reliable either.
We're probably not going to do a "real" share feature for this view, so I think we'll leave things the way there are now.
