This looks really cool! Although this disclaimer is concerning:
"This tool could in theory break if either the Plex database schema changes or IMDB stops providing a public rating dataset! This would not be dangerous tho as it stops when something goes wrong."
Wasn't trying to rain on your recommendation by any means. Looks cool! However I don't know about you but my phone lights up like a Christmas tree from friends and family if my Plex servers are having issues!
