In TB 115.10.2 using Unread Messages view as well as all folders. The unread folder view is a bit brain dead in that if I have unread messages in 3 or 4 accounts then those folders continue to show up in the Unread message view even if you read those messages. It remains so even if a single new messages come in later.
It would be nice for the Unread Folder view would collapse if there are no unread messages. There currently is a couple of round about ways of accomplishing this including restarting TB, fiddling with folder views chevrons < >
