I would like there to be a fourth type of icon to mark a rare with, one of which you still have a new transmog item to learn from.

For example there are rares that still have to drop a mount, which have a skull. Then there are those that indicate a missing toy, which have a chest. But then there are those that have a missing appearance, they are however unlike the others, all marked the same.

I'd like to request a different icon for those that are still missing a transmog, to go along with the theme of items, a chest plate inside the star would make a great icon for the star theme. For the skull theme I'd think a blue outline would work well. Lastly for the circle theme I feel like a star in the circle would be a good icon.
