A KubeJS addon that lets scripts build real, interactive Minecraft GUIs - buttons, toggles, text fields, sliders, dropdowns, item icons, progress bars, tabs, draggable/resizable windows, scrollable lists - all from a single fluent builder, no Java required.
KubeJS scripts can already react to the game, but building an actual custom screen normally means writing a Java mod. KubeUI closes that gap: everything is exposed to client_scripts through one global (KubeUI), built on top of the same layout system (GridLayout, ScrollableLayout) vanilla Minecraft's own option screens use - so it looks and behaves like it belongs.
