This add-on allows users to duplicate nodes across the Compositing, Shader, and Geometry Node editors while retaining their existing keyframes, drivers, and links. It circumvents the default Blender behavior where duplicated nodes lose their animation data, preventing the need to manually copy fCurves or adjust driver data paths.

The Lite version is intended for basic use and restricts functionality to copying one node at a time via a sidebar UI button, without keyboard shortcuts. It successfully copies the last fCurve added to a node but does not support duplicating node groups, multiple simultaneous nodes, or complex RGB/XYZ attributes.
