Debug Rationale for why user can/cant access thread/ function

[mako]

Im trying to understand why a given user can or cant post/ do other functions in a thread.

If there is a number of permissions the system has to work through, is their any way we can see what the problem is and why the user is allowed or disallowed that function, by seeing the system logic for the decision?

Does that make any sense?

Permission viewer plugin may be of some help.
It throws a lot of warnings in PHP8, but seems to be fully functional.
It allows you to see all permissions of a given user.
