I agree that the display of outdated addons in minion could be added to the list view.
Right now it is only visible when you click on an entry in the list:
Adding it as a background color or some icon that shows it is up to date towards the API would be a nice feature.
It is true that some of them continue to work even after the author dropped support. It would be nice to have a voting system where users can declare that it is still working with the current API. That is again something that needs to be added in minion and to esoui and not something an addon can solve.
