This addon has a lot of potential and I wish the developer good luck! It would be neat if it could display likes/dislikes for videos that have them turned off (although some may say that's a bit unethical so I don't know if it should really). Right now it seems like it does display dislikes for videos that have them turned off like with this video https://youtu.be/AgbeGFYluEA but that might be just something with youtube originals
