This is great, but why start with Safari and not a cross platform browser? Is there something native here that can't be done otherwise or is it just personal preference?
True, but that's a way harder problem to solve. For me what was important was reducing the noise as much as possible as fast as possible consistently. Youtube algorithms has been pervasive enough that anything that moves the scale down even a little bit was worth the effort.
It's free on GitHub for anyone to build, use or fork. I've built it for myself, but going through App Store submissions took me 2x the time, hence the price.
I'm in the wrong business.
