On which of my Lists does this appear?

With the most recent title page updates, we have lost a user-created script that highlighted on which lists a title (or person) appears. It would collect data via Export, store it in memory, and when you moused over a link for the title/person, show you all your lists (and your rating, and IMDb's rating) where the title/person resides. (It also colorized the link per custom specs.)

Since I have over 100 lists, it's very difficult to scroll through the add-to-list dropdown menu to see which have checkmarks where.

It would help if the dropdown would optionally sort by where the item is already listed.

Also, it would help if I could do an Advanced Search and select multiple lists, but that logic is AND when I would need OR. (An option to choose AND/OR would help in multiple situations for various parameters.)

Of course, if you could provide the functionality of the now-dead user script, that would be the best.
