I perfectly understood your screenshot, I was trying to say that 95% of it was redundant, and a lot of configurations wouldn’t make sense and be confusing.
Like this one:
It would be see/reply/create for all logged in users, the bottom line would be redundant.
Yes, that makes sense. everyone is treated in a special way, it would make sense if trust_level_X would be treated like that as well. Now that would be a good simplification of that page!
