Readwise's Reader is the best annotation tool, they integrated the great highlighting UX of Reflect, but also did a decent job on how you then manage what you highlight. I don't want to click two buttons to ingest an url into both Zenfetch and Readwise, are you planning an integration / open API?
I actually use Readwise as well! For a workaround I imported all the URLs from Readwise into Zenfetch but a full Readwise integration is on the roadmap.
