Would love this as I see it in other scholarly readying apps (Proquest), as well as Kindle....etc
I approach this slightly differently, working with Pocket to clip articles, then highlight in Pocket > which pushes the highlights to Readwise > which pushes them to Evernote. So I end up with only the Highlighted text in Evernote, and the full text in Pocket. Not idea, and quite the workaround.
