Node Arrange is a Blender add-on that automatically lays out node trees with one click. Regardless of node tree complexity, nodes are arranged, organised, and aligned, with adjustable settings.

Data-Block Utilities is a Blender add-on that runs from Properties ‣ Scene Overview. It shows data-block users in a filterable tree, merges duplicate node groups, materials, images, meshes and lights, and scores node trees by similarity.
