Show What Lists a Paper Was Added To In Its My Library Description
Currently I do not see a way to find out what lists a Paper has already been posted to in ReadCube other than to click on the list and look to see what papers are there.
What I think would be helpful is to show the lists under the title in the My Library's pane. This would be something akin to how GMail shows you the Labels that you have assigned an email to.
I am thinking that this information must already be in your database, and you would only need to write it to the display.
Anything that isn't in a list could be blank, or have an unassigned tag.

If the function to add tags is implemented, perhaps automatically include the library/lists it's in. E.g. "library: [list name]"
