A really useful tool. I read a lot of books from fiction to poetry to non-fiction, and Snippet helps me to get the most out of my Kindle highlights and notes. I highlight text for a variety of reasons: as a reminder to do further research of facts in a non-fiction book, or to save great examples of language, dialogue, characters, etc., in novels and poetry, but also phrases which trigger ideas for my own writing.
I really like the way I can list my highlights by book or author, sort them into sequence, use the Kindle highlighting colour codes to categorise them. Then, when I'm ready to refer back to my highlighted sections I can display them in my browser and/or download them to a PDF or other text format onto my Laptop. Very happy with the way Snippet does all this.
This is one of my favorite Firefox add in’s and I hope it has long sustainably. The only thing I would like to see fixes is all text highlights on webs stays highlighted. There was another add in that I used before where the highlighted text snippets always stayed highlighted. Instapaper has this functionality too so maybe their code can be looked at.
