Hi, I am a PhD student and often have many pdfs open at once for my many classes each week. It would be nice to have a feature that works like chrome tabs, where I can group tabs together and name them. That way, I could be preparing for one class session and have all my readings together and marked for discussion. Alternatively, if I am simultaneously working on separate projects, I could have them grouped together and clearly marked in the tabs to navigate between discussions with different groups of coauthors.

Thanks
