OK, so either way too many people have send on enter enabled or they used their send button as a period. 😉. I would love a setting like "do not play notification sound again within <x> seconds of another message sent by the same person". Add in that the timer gets cleared if you respond. Maybe a pet peeves, but I hate when I'm in the middle of something and someone bombards me with 5 or 6 rapid fire texts and each one is notifying me. 😠
