Similar to how Facebook has a separate tab for messages from friends, and messages from non-friends. I frequently receive spam text messages from unknown numbers. I would like a way to filter out messages from numbers that aren't on my contacts list, so that they do not appear on my primary feed. Notifications from the "other messages" tab would be muted.

I would also like for Textra to intelligently mute notifications from certain numbers if I receive (but do not respond to) multiple messages from the same number.
