Unless the street is almost clear of activity, whenever I get one of those sparkly rainbows, it disappears before the letters are displayed across it. Through trial and error, I know what most of them mean now, but if the animation can't be fixed, can we at least get a text notification in the log of what the thing said?
This would also be good for instances where something pops up in the foreground and you can't see what the rainbow is saying behind it.
