I would love to be able to add someone into the contacts directly from a received or sent text message, and that the system recognize duplicated phone numbers and merges them as one. I received a text from someone and when i added them as a contact and i started communicating with them via the named contact messenger, it does not connect their old unnamed thread with their new named thread. That seems silly and it is also not helpful to have the 2 separate threads with the exact same phone number.
