I thought it would be nice to have a little bar...like your inventory, which you could move around and hide such, that would have your emotes on it. It could have pages or something so that they would all fit.
They could be listed by their name (Cheer, Bow), or if we got really fancy, it could be listed with a little graphic.
Anyway, I am not good enough at skinning to do this, but I always thought it would make for an awesome interface element. Especially with the multitude of emotes that LOTRO already has.
