I'd love to be able to organize my photos so that when I am scrapping about a particular thing, I could pull up only those photos.

Alternatively, I'd like to be able to add folders to the Places Bar. I have my photos on an external harddrive. I'd like to be able to add that drive to the places bar so I can quickly get to the pictures folders there.

My first preference is to be able to tag my photos and bring up only those photos which fit the category. Somethink like HP Photosmart Essentials.
