About this project
What does Cumulus add?
☁️ About Cumulus ☁️
Cumulus is an API made for allowing developers to register custom main menus for their mods, while not conflicting with other mods' menu screens. Registered menus will be listed in a new GUI accessible from the "Menu List" button found on the main menu, and from there the player can select which one they want to display.
Cumulus also includes a world preview feature that allows the player to pre-load their latest world from the title screen in replacement of the panorama, while still retaining other UI elements. The player can also quick-join and leave between the world and the main menu using this feature.
