What is Ultra Customizer?
Ultra Customizer is an entirely new plugin that replaced Hydra in every aspect. It offers all the features that Hydra had but is now much easier to use and you can do way more than you could do in Hydra. For example make action based Scripts like on block breaking, player joining and so much more. The possibilities are now literally endless
How do I transfer my data from Hydra?
Transferring your data is not possible because it is an entirely new plugin. But dont worry because you can use Ultra Customizer and Hydra at the same time.
Whats the new Command / Permission?
The plugin only has /customizer which requires ultracustomizer.admin
