Everybody who sometimes or always plays on PC knows the struggle when they get a PM and have to scroll through their long long long long long list of friends to see who the message was from. Straight to the point, it would be nice if recent messages popped up at the top of the list on PC, like they do on iDevice and other mobile phones. Also, once you have opened the message and possibly responded, the conversation should STAY at the top of the list!
This has been requested for ages now. Not sure why it hasn't been implemented yet. Would have rather had this than an alphabetized list. Support.
