Wardrobe in the hub
My idea is described in adding a wardrobe to the hub. Why is wardrobe better? It will replace all customizable items in the hotbar into one: Dressing Room. And you do not have to search at the bottom of the hotbar and spend a lot of time on it to customize your character.
In the dressing room itself, you can notice several categories. Here are some of them: title for the hub, means of movement, headgear, pets and much more.
If you like my idea and have something to add, feel free to write in the comments what you can add/remove.
