When I’m reading to learn, or when I’m reading for something to write, it helps me to mark key passages. Collected together, the passages give a personalized summary of what I’ve read. They’re immensely useful as quotes and references, for future writing and review.

toggling back and forth between apps while copy/pasting distracts from the reading experience. It’s even more cumbersome to do this with the smaller screens and slower processing on a phone or tablet.

Fewest Actions. Highlighting should work with the fewest number of actions possible. The reading is most important. Distractions must be minimal.

Portable Highlights. I do not want to have to copy/paste every time I make a highlight, since that’s already what I do now. I’d like my highlights to be portable, especially into plain text files for use with my other notes. I’ll need a link back to the source to come along with whatever I’ve highlighted.

Capture Anywhere. I read on Windows, Linux and Android systems, running on desktop, phone, and tablet devices. I need to capture highlights while reading on any of those.

I found it irksome that the exported highlights didn’t link to the original source, but to a copy of it on Diigo. This is done in order display the highlights along with the text, but I prefer text fragment linking for this.
