It would be great to have an option to view your notes as a column heading in the library. This would enable you to view all your notes relatively quickly instead of having to click through each individual paper.
I agree! It is very hard to skim through papers by title. in Papers3 the "notes" column was vital to finding key articles quickly.
Papers3 had this feature. Now it is taking much more time to find what I want in ReadCube Papers....
We have implemented this in the latest update.
