I think it would be excellent if Minion would read the API version from the add ons and then if it doesn't match the current API version that's live it would put a little icon indicating the add on is out of date, especially those you might download or want to uninstall if they stay out of date.
The attached pictures is a sad mock up but gets the idea across. I also have no idea if the two Add Ons I labeled are out of date, just examples.
