Mount Stable
Collecting and summoning Mounts now works similarly to Cosmetic Pets.
Double clicking on a Mount item will redeem that item and place the mount in your "Mount Stable". The Mount Stable is a new tab of the Inventory Menu that contains all of the mounts that you have redeemed on this server (regardless of which character redeemed them, like with cosmetic pets). To summon a Mount simply either double click on the desired mount from within the Mount Stable or drag it's icon onto your hotbar and click it there.
Plans for the currently existing Mount Bag item are to be determined.
