We don't have anything for auto reordering, though that would be a cool mod. You can, however, do a search for the pointees and sort them dynamically.
I assume you've noticed that you can drag and drop pointer items?
Uhm. I haven't actually. Does the pointer change in Chrome to indicate that you can do that? It doesn't in Opera, which is probably why I didn't think it was possible, although it will let me if I click and drag on either side of the X. Anyway, that means I don't have to worry as much.
I'd rather not make a zillion searches for everything since there's no way for me to hide those cards from people. I'm already trying to name them things that are obtuse and meaningless so they don't show up in searches. Also, I'm not sure what I'd search, since the idea is that people are manually creating the list. Although about making them searches of pages that link to the card in question, but it's possible to talk about a character without them actually appearing, and the list is supposed to be times that they appear.
