A mod with several small tweaks that aim at giving the server admin more finite control of the server. You can disable travel to the end, nether, have fake hardcore hearts, toggle the "Join-ability" of your server for everyone but ops so that you can stay in a sort of maintenance mode without needing to change permissions.
Syntax:
the /config configured command is used to control the settings in game, the configuration is stored in ./config/configured/config.json relative to the server's directory.
