Browser certificate user interfaces are atrocious, they hasn't changed in about two decades. They should...
- have a list of favourite CAs you might want easy access to temporarily (dis)enable
- be able to show CAs in a tree view by continent and country so you can disable everything inside a selected branch because you're never going to be interested in them and they'll only be a cause of security problems
And that's off the top of my head.
Biting the hand that feeds IT
