Random favorite minipet autosummon hooked on forward moving. Your pets will never get randomly lost again
How it works:
When you start moving forward addon checks if you have minipet summoned already, if not and if you're not in combat and not mounted (etc.) then it will summon one from your list of favorite pets.
In 5.0 it's the same, Ctrl-Click can set pet as favorite along with blizzard's dropdown menu.
