Add a unread filter or tab to the Inbox

[NoeDeMontard]

Hello,

It would be nice to be able to see only the unread messages in the Inbox's message list.

I personally get a fair amount of messages and don't always read them in the order of arrival, causing some old messages to be buried.

Thanks for this app !
