99% of the people in my contact list are "emoticon-friendly", but every once in a while there are people that just abuse the custom emoticons and make their chats practically unreadable. They make you want to turn custom emoticons off. However... I love custom emoticons, just not the ones from that particular person. And kicking them out of my list is a bit too much, really.
So, I'd like to have the ability to switch off custom emoticons for a particular person, so that they don't show up in conversations with that person. Not sure if it's even possible, but hey, suggesting is the least I can do
