Version : 1.0.1 ~
What's new:
To use the plugin you need to have the unluckygui.manage.roles and unluckygui.use permission nodes.
I recommend just having the unluckygui.* since i just played around with how permissions work and got to lazy to remove the other nodes.
The commands are pretty much the same.

I also added a config.yml with some useful configurations like setting up the server context (default to "survival"), enabling show-context and show-expiration, changeable Menu Titles and success messages!
Next update ~
Better Go Back navigation (I had to redo the whole thing for consistency and it works poorly now).
Solving some minor warns in the code.
