I've been building something in a similar space over at https://muted.io/. It's been just about paying out my rent and food in the past year.

I've been pretty impressed at Lightnote and how its executed and actually tried to reach out to the creator a couple of times for potential collaborations. Not sure if my messages made it through.

Thank you! And yep, I made it.

Really not sure what does that. Not using any JS scrolling library. Perhaps a performance hit from using backdrop-filter on the table of contents section for a background blur effect.

Thanks for pointing that out, fixed it.

Fixed on ::marker, not on ::selection ;-)

Oh thanks for pointing that out! Weird bug in Safari with CSS animations it seems. I found a way around it and it should now work as expected.
