Interesting that you say that it's faster and more stable. My 2013 Air is on Monterey and it's "good enough" for my needs still, but slipping towards not quite good enough. Very tempted to give OCLP a try if it extends the life of the machine a bit more.

I've found on my streaming device that Netflix is seriously fast at buffering and playing once you press play compared to D+ and Prime. Like 2 seconds vs 10+ seconds. Of course could just be my device but seems like they have really optimised the UX.

You're right, even with the "autoplay" settings turned off when you drop into a TV show's subsection it will automatically start playing the next episode. Incredibly frustrating when you just want to check episode length of number of episodes per season.
