Add custom column to Entry Type index page I'm creating a plugin and I've been following the Mijingo Craft plugin development videos. I reached the point where a column was added to the entry index page. I was looking to do something similar but on the Entry type index page /admin/settings/sections/{ID}/entrytypes.

I was unable to find anything in the documentation (maybe I missed something). But is there a method I can use to do this? or is it not possible?
Unfortunately, that's not possible currently.

If you feel that a hook for customizing the Entry Type listing/index should exist, you can add a feature request.
