With Papers 3 you can organise your library with various identifiers to help you keep track of your research. There are two ways to do this in your iOS app.
- In the main library view, if you swipe horizontally across an article, the card will flip, allowing you to add your colour labels, rating and flag.
- If you are already in the reader view, you'll see an 'info' icon in the top right.
- From the info view you can add a star rating and flag the article. Additionally, on an iPad you can also add a colour label here too.
