This IS the holy grail of Add-on enhancements. The update which I read through today is mindblowing. There's so much effort gone into this YouTube Enhancer. To be able to have custom colour palat option for the YouTube specs is awesome and actually really good fun. Some options are a little over my head, but I intend to read and learn..To start with: Give me a custom Dark theme any day. I don't stop enough to buy the dev a coffee, but I did on this one. Thanks a million Maxime RF
