I am working on making it easier to manage mute lists. One realization is that the entire mute spec is broken/badly implanted. Private mute lists don’t work except on a few clients. And if you edit your mutes on two different clients they can completely overwrite each others’ lists.
I hadn’t discovered a good way to backup mute lists yet, so I started building Mutable. It’s still a work in progress, but it’s getting there.
