Easy Modifier is a Blender add-on from CG Tools built to manage modifiers on objects. It gathers tools for adding, changing, applying, and removing modifiers into a single workflow, with panels available for the add, change, and remove options.
The add-on works through four modes—Add, Change, Apply, and Remove—each paired with four selection options. The All option affects every object, including inactive ones; Selected affects only selected objects; Collection affects a chosen collection; and Visible Objects affects the objects seen in the scene.
Apply mode includes a backup capability for saving an object's earlier state before modifiers are applied, plus an Apply all modifiers button for one or more objects. Remove mode offers a Remove all modifiers button and an option to remove keyframes. You can filter modifiers by name in all panels and adjust keyframes for individual properties. A demo video is available.
