Here's your 5 stars. Plugin works as intended and functions without failure, as to "Blake164366"'s comment regarding "1", he means that even if you are invisible, you should be able to still see yourself, this is a way to confirm you have enabled invisibility and that other players that aren't staff or something like that cannot see you while you are in vanish mode. Hope this clears the confusion up! :) Good work!
3/5 good concept but here's what its missing. 1. The ability to make yourself invisible where you can see that you yourself are invisible. 2. Add the ability to do /lp on and /lp off as just two extra commands that are helpful. Overall a nice little plugin.
