I use a specific discord channel and slack channel that I'd really like to get notifications for, but have a ton that I'd rather not. It currently seems I can't get any notifications from channels, but can from direct messages.

It seems there's a channel mute option, which I would think would mute notifications from that channel. So maybe this is just a bug?

I do have all of the options ticked under notifications in general, for what it's worth.

Notifications rules editor (like a big table you can edit per-channel) is in the works.
