Open Messages Side by Side and then Tile
I don't think I'm the only one that might want to read more than one text at once. It would be great if they "auto-tiled" similar to your "Power View".
You might be planning something with 3 friends and being able to see their responses would be great.
Perhaps an option to create a chat and you just drag the contact onto the chat. Of course a contact could be in more than one chat because it's just a view.
Regardless, me likey mighty.
