PruneKit: Catalog Pruning

PruneKit: Catalog Pruning helps merchants identify which designs actually sell and which ones do not, then bulk-hide the underperforming items by setting them to draft without deleting anything. It organizes products into performance tiers such as Winners, Solid, Slow, Never sold, and Too new to judge, using sales data net of refunds while ignoring views, and it also supports filtering by tier or tag, unhide actions, and full undo history for safe catalog cleanup.
