Would it be possible to add in a "special" group segment where Moderators and Administrators have their own special dropdown box segment in addition to the normal users segment?
So as per
your image here... the moderators would see:
-- Select an Option --
Correct Spelling/Grammar
Add Relevant Content
Remove Controversial Content
Attach Image Inline
Wrap LaTeX In Tags
-- Moderators --

Normal (non-special/non-elevated) users would see just the Select an Option portion with out the moderators portion. I think that would complete this addon. :-)
