Chat tab filtering persistence, or a default option to filter for unread chats
In general, users use the Chat tab to interact with their peers.
While it is nice to have historical messages there, the primary function is to read and respond to new messages that have come in.
There is an option to filter for only unread messages as the Chat tab will get very cluttered.
However, if you navigate away from the Chat tab, the unread filter is no longer applied.
It would be good to have filter settings stick if you navigate to another tab in Teams or have an option for the default Chat view to be unread and the option to view all if you need to reference historical chat messages.
