It would be very useful to know in which lists a given reference is. That would truly help organize all lists
Just want to chime in that this is a pretty fundamental feature of the List system, because without it, you can't find all the other papers that are related to this paper.

Yes. Really needing this back. Thanks.
Yes! Important! Please implement that!
