Solved Rights needed for 'delete permanently'?

I've done some searching on this, and I don't understand the system.
To be able to get the 'delete permantently' button, it seems that I need to assign the 'configure' right in the ACL in options.
I'm not sure what the logic in that is, and for me the problem is that 'configure' also gives full access to all the forums, which is not desirable for our setup.
Could the 'delete permanently' be moved to a seperate ACL entry, or could it be that if you were assign to be moderator, that it could be allowed?

You need to be an administrator to be able to delete permanently a post or a topic. See Kunena Features in the Wiki.

Ok, so as I understands your answer, currently if you wish for a user to be able to delete permanently, he also gets full access, despite group access settings.
So my suggestion for a future implementation is that it would be nice to move that to a seperate security setting.
That way I don't have to allow my designated forum person to also have access to the full forum (where there are semi-confidential discussions going on that he is not to be involved in, or have access to).
