So clicking on a mount icon will get on the mount as normal.
If you click on a different mount icon it will get on that mount.
If you click on a mount icon your already on it will dismount.

Simple game logic.

Maybe too complicated for some programmers out there.

Someone will tell me there is a dismount key. I'm thinking about people new to the game and or mounts.

Coders should be trying to make life easier for the customer not making it easier for themselves.
