Actually takes the Gameshop pets a place in the backpack. You can`t throw them out your package. The mounts are bounded.
That is the Idea for a new Button = Mounts
All Mounts that you have buyed in the Gameshop are activated in a Special Mounts Window.
Have you buyed some Mounts is that a simple click and the Mounts spawns. All other Mounts that you can buyed but not have, are Greyed.
But you have more Buttons for Mounts, Skills and things to build...or items.
Short: The Toolbar get smaler...you need more place.
Here is a example with 2 places more...
