Something I've noticed as well with the PMd is that when they are shuffled into the folders and I get a new PM, it's not always clear where the PM is if I go to the inbox with the selection menu first, rather than notifications 

Sort of like:
"Not in inbox, maybe trash? Nope. Archives? Yep. Ah that's right... Needed that PM"

Could some extra clarity be eventually built into the folder system?
