Since I've seen this requested before, and I wrote my own Chrome script to fix it, I figured I'd share. I started using lists once I found out how awesome "ABitBetterRTM" is, and I just needed to shore up the last bits of missing functionality. :)

Helps make lists as flexible as tags on Remember the Milk. Shows list names in grey to the right of task names in task lists (similar to how tags show in blue on the left or right). Also makes list names into links, when shown in the details pane on the right.

Note that both of these features only apply when looking at a Smart List or search results. Within a normal list, it is assumed you understand that all the tasks are part of the same list, and the list name doesn't show in the details pane.
