Simpler and faster Category Settings page

I’m not sure I’m following this…?
For example if I have all the groups visible and I tick “Reply” on the everyone row, all the boxes get ticked for all groups.
So wouldn’t it make sense that if I tick “Reply” on the Trust Level 1, it would tick for all above that as well?

What would be the result of something like this, for example, if they are indeed subsets of each other?

That’s why I said it could be just an option, because each user has their own experience. For me, it makes more sense to see everything, the same way that lots of Wordpress plugins show all the roles without having to add one by one.

You misunderstood my last screenshot. That image shows the default state when going to that page for the first time and then I would tick the boxes I want. Similar to Wordpress:
