This seems like an obvious thing, so perhaps there is a reason why it hasn't been done yet, but would it be possible to quickly take all the highlights in a book (or collection) and convert them to a clippings file?
This would be really helpful for revisiting themes of a book later on. Particularly commentaries or reviews of popular books.
Better yet, export either all highlights, or just highlights with a certain pen. I often use a different color to highlight something that I disagree with. Grabbing just these would be great to prepare a book review for a congregation.
Perhaps there is a way of doing this that I haven't come across?
