Yeah, there are a few core features that can really make or break a notetaking workflow. I'm on an iPad (I need full color pan/zoom for my core workflow) and I want to love ZoomNotes so badly, but the OCR search is slow. It's a silly problem -- it goes one document at a time every time, so probably OCR caching is janked out or something -- but it's core enough that I am willing to cut out all of its considerable feature library from my workflow and use a much simpler app, GoodNotes, instead. It barely meets the core subset of features that I absolutely need, but none of those features are broken, and that makes it a winner.
