> I want my notifications to be a mini-inbox, where I can view notifications, respond to notifications, archive completed notifications, and filter notifications into channels (the same way I can filter emails). This is exactly how the most recent release works, no? Notifications are "unread" by default, but "read" when you see them -- however they stay in the "Inbox" tab of the notifications panel. You can reply directly from there, or mark them as done by clicking the "x" to remove them from the Inbox. Everything you described but filtering.
