Description from the author on Modrinth

With the "kusakaUI" plugin by Bronka, you can create a user-friendly interface directly within the game. You can build fully functional elements, such as shop menus and more. The plugin uses the following commands: /km and /ks. The /km command allows you to create an interface or edit an existing one, while the /ks command lets you open the interface in "player" mode, enabling you to test its functionality.**
