This add-on manages automatically displaying and hiding the small area map when riding a mount.
The area map is normally toggled with the shift+M hotkey combination. Upon completion of casting a mount, the map will display. Dismounting will hide the map if it was originally automatically displayed by the add-on.
If you manually display the map by using the shift+M combo, the add-on will not automatically hide it - you must hide it with the hotkey as you normally would.
As an added bonus, this add-on also fixes a client bug where displaying the map doesn't retain the player's transparency setting.
If the map is not triggered by your mount, please leave a comment and I will contact you.
