Better owned marketplace items management

Allow for items gotten/purchased from the marketplace to be better managed.

For example, adding favorites, an option to hide select items or even the option to remove (free) items from their account (like capes or cosmetics) would help players to easily organize their account account and keep a more clean and organized look.

Also allow players to display their items (capes, cosmetics, etc.) in a kind of profile tab which can be seen in-game would also be a great addition.

These additions would not only allow users to have better control over their account, but also make the skin select/ character creator tabs feel more organized and polished.
