Ask HN: Practical Resources for Progressive Disclosure, Adaptive UI?

I've been thinking a lot about user interface design lately. Specifically, I've been thinking about breaking down large applications supporting myriad of specialized user workflows.

I'd be grateful for any shared material you've found helpful for building systems that employee these concepts.

P.s. I've been failing to find a blog post written between 2021 & 2022 that broke these concepts down nicely. The site appeared to be using some kind of graph paper background if that helps ring anyone's memory. I can't place it exactly, but the author discussed applications that would dynamically pop-in features relevant for users' workflows.
