I agree, nice work @Chris27 (and @lionel-rowe) 
Taking this one step further and especially thinking of those using custom settings, is there an easy way to automatically create something like this overview from the settings? Maybe using some form of SQL queries, or even using the Discourse Data Explorer Plugin by @riking
All the necessary information should be in there, right? This would reduce the likelihood to make errors, but also make it easy to update the table I think.
Taking this two steps further, could this also be done for plugins that have trust level settings?
Taking this three steps further, this would be an amazing interface to manage these settings as well, as it’s very hard to get acquainted with rights management as a newbie like me (I get easily lost with the admin interface sometimes 
). However, I imagine this being much more complicated than step one and two.
PS: I have no clue about SQL queries at this point in time, I’m just interested if it’s possible at all?
