I was reminded of this old idea and decided to step up the fidelity to see if I would learn more about it.
I have a feeling most highlights will be full sentences, so it could just be that, tapping a sentence and done. Which reminds me that it’s odd Kindle’s highlighter doesn’t default to sentences.
It would also be cool if this one could remember pages and add the highlights when it sees it again.
It should probably also save everything it saw as an image so you could get the context of a highlight.
