Do you use Matrix? I have a group chat with a couple of the other frontend devs if you wanna join the discussion there.

We setup this GitHub to write the spec, but I haven’t made much progress yet. I’m trying to close out a few other features (e.g. post/comment moderation, PieFed feeds, PieFed polls, PieFed events, etc). But I think I’m pretty close to this filter engine being my top priority.
