Marc and Steven have their names in front of their icons so it's easy to find them. Midnight has ZZs in front since I don't need those as often so they can drop to the bottom of the list.

After that it's just keywords that help me remember what the picture is, because with my cruddy eyesight I'm not always able to see the nuance of expression. Which does have me worry sometimes if someone hovers over them because the keywords aren't necessarily what the icon is just what I'll remember. For example, Steven has an icon that's "unsure" but that's just for me. It doesn't necessarily indicate he's unsure about what the other character is saying.
