it would be really cool if you could take conversations and add them to a folder to help tidy up the main activity. when you touch the folder it will open and show all of your conversations and any new messages to one of the conversations will be sent to to the conversation in the folder and not show on the main screen. An example would be to put conversations with family or automated messages in their own folder to make it easier to find them or to keep automated SMS out of the way to keep things tidy.
