For modpack creators and developers, FTB Library offers several extensible systems:

  • Sidebar JSONs: New sidebar buttons can be added by placing JSON files in assets/<modid>/sidebar_buttons/. This allows non-FTB mods to integrate with the sidebar system.
  • Icon Class: A reworked rendering system that handles textures, item icons, and even remote URLs for UI elements.
  • Team Integration: While FTB Teams is a separate mod, FTB Library provides the underlying UI components for team management, color selection, and member lists.
