Delete Useless Shapekeys

This add-on automates the deletion of inactive or insignificant shapekeys in Blender. It evaluates the vertex offset of each shapekey against the Basis shapekey, automatically removing those that fall below a user-defined distance threshold. Users can adjust this threshold to account for floating-point precision errors or to clear out shapekeys that provide minimal deformation. The tool is accessible directly from the shapekey context menu and includes a confirmation popup before execution, as well as a status notification detailing the number of shapekeys removed.
