i wish Apple would've applied the same Peek Feature in the Messages App that they did in the Mail App. Im constantly Peeking at messages and i alway's slide left to delete the message and i do this about two to three times before i remember I'm not in the Mail App and i can't do that in the Messages App. This is my only complaint about 3D touch besides that not enough App's have it yet but i realize developer's need time to implement it.
