Adding categories support to albums

I’m trying to see for I can best use categories and I noticed that albums didn’t get them.
I’m really hoping that there’s a way as this would provide a way to easily see of a photo is already in an album.

For example having an album called birthday that contains the name of people that I use to tag their birthday photos as subalbums. With the inherited feature of categories I would then be able to see at a glance if a given photo was already tagged for a birthday.

Anyone can think of other uses for categories in albums?


I’ve started using them as a way to track what I’ve exported, or what side of the family the pictures are. I can do this on the folder level, but I sort them into albums and to mark it exported, having it in albums would be way easier.
