I'm not sure what all MiniPet does, but here's how I manage my minipet collection:
1. Download and install Menagerie to auto-swap minipets when you visit the bank.
2. Make a macro to use the item in the bag slot where you keep your minipet(s):
/use 4 1
/userandom 4 1, 4 2, 4 3
3. Drop the macro on an action button or bind a key directly to it with SpellBinder, BindPad, or any other direct-keybinding addon.
