helpful ,Great designer/coder quick to fix when utiube break his work. personally been using Dishita's add on for over 10 years and must have archived at least 3tb of high quality videos ripped from ytube for 10+ years! 100% legit Dishita is a pro and for a one man operation his add on is epic and he is as skilled and quick as a team of top developers to fix things (rarely when ytube cracks down) 11/10
