I'd like to see image categories in addition to album categories. ACDSee has a great feature like this. A single image can be in multiple categories. I've set up categories for albums so an image can be in multiple albums. I've got a collection of categories for people organized by families. I've got a set of categories for location. The possibilities are endless. The categories are then presented in a pick list so that by selecting one or multiple categories one can create a custom album on the fly. You can imagine a boolean filter of the categories to create albums as well. A pick list of existing categories would also be used for entering categories for a specific photo.
