First of all, I suggest that you remove and readd the following. This is just to be sure that your players won't have access to the following commands without permission.
This update includes a new tab in the settings as well as a command to be able to enable/disable the plugin for players and yourself.
The command works as followed /crop toggle which will enable/disable the plugin for you and /crop toggle <Player> which will enable/disable the plugin for the player.
New Permissions: cropclick.toggle and cropclick.toggle.other
