<label>This extension will re-layer your selected items or the whole document according to their style values (stroke or fill).</label>
<label>The filtering applies only to style attribute of the elements. It does not filter for stroke or fill if they are set separately. You can use the separate 'Cleanup Styles' extension to migrate these separated attributes into style attribute.</label>
