I'm running a pretty detailed story, and I'm finding that even though I've only set up for the first two scenes, I have more cards than is easy to keep track of. Right now I'm maintaining them in a spreadsheet, but it would be nice to have some kind of filing or tagging system where, when I'm setting a scene, I can search for all the cards that belong to that "group" rather than having to manually figure it out from the pile in my narrator screen.
