I haven't spent a ton of time with the feature, but I do like it quite a bit. It's fun to have what amounts to a personalize-able little card in game and there's a lot of creativity I've seen from people a bit more familiar with the options/posing aspects -- and I think that's really neat.

More text to write in the field (possibly even separate from search info) would be nice, I imagine, to people in the RP side of things as I can see these being really useful ways to provide small blurbs about a character in-game. I'm sure there's other ideas that'd be good, too, but I kinda like that one since the search info always felt just slightly too short to me from time to time whenever I wanted to post my dumb BS.

Being able to see them in more pieces of content could be pretty cool -- the instant portraits, at least; though I assume that's already in the Devs' heads considering the instant portrait is only used for PvP currently and it's not called "PvP Portrait Display" or something similar.

But I really like the feature, a lot more than I figured I would to be honest.
