I think it would be extremely beneficial to implement an in-game search bar. If you are anything like me, you are constantly using the Destiny app to transfer items. And it is rather tedious to move items around your characters, especially if you are moving an entire load-out. Adding a search bar in your menu that would allow you to take any item from your vault and any of your characters would save so much time. If you can move items around with your phone, I don't see this feature being overpowered, as it would only save time. Like if you agree with my points so bungie can see this and hopefully implement this as well.
