Agreed. The signal to noise ratio in my newsfeed is very low because of it. There exists some workarounds (e.g. https://www.codeshelver.com) but I'd like to see GitHub fix the problem.
I'll give it a try in a few days, but just a question: what happens if www.codeshelver.com dies tomorrow (assuming they save shelved repos on their server) or their Safari extension be buggy and it removes/corrupts all my precious repos (assuming it's the extension that saves the repos)? Will I lose everything?
I can't answer your question because I don't know about the inner workings of CodeShelver, but it's safest to assume you would lose everything (going off the assumption that they store the info on their own servers).
You should also check out Gitmarks. Someone posted the link in a reply to my earlier comment.
