The ability to select multiple lists at once would be nice. Just a bunch of on/off toggles for each list in the selector so I can manipulate & filter the feed how I'd like.

Do you need to set up multiple list sets as feeds so you can go back and forth between them?
I was thinking more like just a filter tab. Treat the list names like tags I can turn on and off. You can select one, a combination of, or all lists.
But lists of lists might be useful too.
nope bullshit idea - that will break thing of fast - small many lists
