The Blender add-on is a highly sophisticated data manager. It can outline/arrange/control all your modifiers, materials, collections (and other data) in currently open file, scene, visible objects. Select, Add, Remove, apply multiple operations on the selected modifiers, materials and collections or filter, search with custom user settings. Manage everything on the fly and keep a complete overview of your project. It is ideally suited for large scenes where you especially need to clean, purge, merge and in other ways reorganize the project data at once.
