Hello there,
so I have been working on the Plugin a lot lately and have a mega update for it now.

Here's the Changelog of the 1.4.0 Update:

- Added Support for MongoDB.
- For future versions, notice if you need to Update the Plugin.
- Made Developer Message customizable.
- Added TabComplete on Command.
- For more accessibility, some config entry names were changed:
-> lacking-permission to lackingPermission
-> use-permission to usePermission
- Completely reworked PlayerData Storage System.
- New Error Messages instead of just exceptions for better and faster Support.
- Changed some internal variable and function names.
- Fixed a Bug where some Data was mixed up.
- Added an API for Developers.
- Added ability to use existing Player Data to create a Player Data Profile.
- Added multi language System.

A few notes:
- The Update may be unstable because it is not possible to test for every single situation that could occure. Because of that please contact me if you found any Bugs or major Issues via Discord or Github.
- There may be a Bug where the Config is not updating correctly, I am working on it to fix this potential bug, but I do not have a lot of Information about it. Because of that potential Bug please make a Backup of your Config before updating the Plugin. If you encounter this bug, please feel free to contact me.
- The Plugin page will get it's update soon, I still got a lot of things to do.
- And last but not least, the sourcecode will be updated in a couple of days. It will take this long because of some technical difficulties.
