I'm not sure, tho' I can guess, there were similar threads, but either way, I would like to see search function (similar to CS's one, cuz that one works pretty good), for at least friends list, but for guilds members could be implemented too. I would find it useful for quick searchin for someone on my friends list and msging him/her directly from there, as it is sometimes easier than writing whole "code", esp. when IGNs are long/tough (if I can describe them that way). Just make search function, and add one small search bar somewhere on interface. Would be quiet useful.
