Ever since the Back to the Mac event, Apple has been bringing the best features of iOS to the Mac with OS X releases. With Mountain Lion, I've noticed some of those iOS features have been improved as they've jumped to the Mac. It's reasonable to assume that many of these improvements will jump back the other direction and show up in future versions of iOS. This thread can be a list of those little things — the things Mountain Lion does right and Apple will likely bring to iOS. Below are a few things I've noticed so far. Safari - The unified search bar in Safari would work great in iOS. Messages - The iOS Messages app creates two separate threads for iMessages to a phone number and email address. (The short of it is that iMessages sent to your phone number only go to your iPhone, while iMessages sent to your Apple ID email address go to all your devices.) However, Messages on the Mac intelligently COMBINES conversations into a single thread when it knows they are all with the same contact. This is great because it works the way iMessages was intended — all your conversations with a person are in one place. I'm sure iOS will be able to combine message threads soon too. Mail - VIP smart mailboxes would be excellent in iOS, especially for the notification alert settings they enable. What else?
