I have two specific complaints with pets getting in the way. One is some of the pets, some of the time, as far as I can tell, have collision as if they are npcs. Pretty obvious how that can be annoying. The other issue is with the winged twilight. When you engage in conversation with an npc and there is someone's winged twilight very near, the twilight will get stay on the conversation screen and flap its wings in your face while you're trying to have a decent conversation. It should disappear the same way that other players disappear for you when you engage in a conversation.
