MountButton

- First release. The mount button from the Shadow Priest addon, on its own, so it works for every class and needs no other addon.
- One button with a key binding of its own. It carries your flying mount where you can actually fly (Outland and the Isle of Quel'Danas, outdoors), and your fastest ground mount everywhere else.
- Mounts come straight from your bags and are ranked by the riding skill they need, so a new mount is picked up by itself. Nothing to set up for a character with one mount of each kind.
- *Ground mount* and *Flying mount* dropdowns, saved per character: *Fastest*, or one mount from your bags. Dragging a mount onto the button sets the choice for its own kind.
- Anything else dropped on the button (a spell, an item) is pinned over both choices. `/mb clear` takes it off.
- Hover the button for a row of your other mounts, one line for flyers and one for ground mounts. It opens up or down, and works in combat.
- Settings window (`/mb`): size, opacity, key binding (keyboard, mouse buttons or the mouse wheel), cooldown numbers, hide in combat, grey out a mount you cannot summon, fade or hide the button while it is empty, and language.
- English, German, Hungarian and Croatian.
- `/mb lock`, `/mb unlock`, `/mb clear`, `/mb status` and `/mb reset`.
