FIXED:

• Many small issues that were discovered down the road.

ADDED:

• Tab completions based on permissions.
• 'Teleport all players' button to teleport all students in the class to your current location.
• Official 1.16 support is now confirmed.

CHANGED:

• The overall menu look is changed to contain more borders.
• Items that are not available due to a certain state (for example you can't delete a class while it's busy) will now have a different appearance to stand out from the normal borders.
• Some spelling mistakes were fixed.
• Background changes:
  • The language system was completely rewritten.
  • The whole inventory system was rewritten to be much smoother and less ugly. I tested the whole system many times, but make sure to test again for yourself and report any issues in the Discord server.

Next update will probably contain the last set of rewriting the plugin. After that, I will have more time to focus on features.
