  youtube.com##[page-subtype="home"] .ytd-rich-item-renderer .ytThumbnailOverlayProgressBarHostWatchedProgressBarSegmentModern:upward(.ytd-rich-grid-renderer)
  youtube.com##[page-subtype="home"] .ytd-thumbnail-overlay-resume-playback-renderer:upward(.ytd-rich-grid-renderer)
  ! Hide stupid "Includes paid promotions" button
