Some of the server commands on the GUI do not require restricted access (such as the dup, which has RTB prefs for admin-only usage), which should.
This could be a very nice GUI mod if it didn't bypass certain necessary restrictions.
Edit: Took another look at the code. Everything should still work normally, since most of the default server commands already have an admin check in the main function, but you always get a message in chat which is somewhat annoying. It would be nice if the admin-only commands had a check on them to return the function
