You can now change, if the tnt settings should be available in the settings gui. Just change the value of "explosionsingui" in the config to false

You can now open the settings inventory for a Kingdom with the Kingdom name! Just put the name of the Kingdom after the settings
Updated the Tab complete, it will now show possible arguments too

You can now change Item names and Messages! To do this, simply change the boolean "generatemessagefile" in the config to "true" and it will generate a message.yml file, where you can change the messages etc. To then apply the changes, just restart the server.
Removed the addadminvianame etc. commands and made it so that you can add/remove admins/members with the kingdom name via the normal commands to add/remove admins/members, but with a 4th arg

This can be changed inside the Config. You can now also delete the Kingdoms of Banned players automatically

When you enter a Kingdom without permission, you will now not be teleported to the highest block, but behind you.

Thanks to Funcybear for the video and giving me the idea!

You can now change the title of the Kingdom, if the Kingdom has a name. The command is
-/kingdom settings title <args>
You can also change the max length of a Kingdom name and the title via the config
