I'm not sure if this would be the best way to handle this but here is what I'm thinking/wondering...

When admin mode is disabled this plugin does a check for flying and turns off NOCLIP if needed but I frequently find myself forgetting to disable Vanish &/or Godmode (plugin). So, would it be possible for these to be disabled when turning off admin mode? i've looked into both of those plugins and unfortunately both of them are pure toggle commands w/o the ability to specify an on or off as a command parameter. 

also, lower priority but a configuration option to PrintToChat that the player has toggled their admin status (along with the text of this message) would be great. (I'm currently using "has enabled their admin abilities" and "has disabled their admin abilities and returned to Player status".)

Again, just a couple ideas that would help. More than willing to discuss ideas if you'd like.
