We get a lot of great ideas about new features, changes to our existing features, or general UX adjustments from our users, and definitely value this feedback! Unfortunately, we cannot keep track of all of these great ideas ourselves.
This is why we created our Feature Request page. Our feature request page allows users to scroll existing ideas and vote for them if they think they're good ideas, as well as provide comments to explain their particular vision. If you can't find your idea yet, feel free to add details about it in the "It would be cool if ReadCube could..." box, which will either find you your idea or allow you to post your own! Please be as descriptive as possible - the better you explain your idea, the easier it is for other users to picture it as a feature!
