THE MOST NEEDED FEATURE for iPhoto is being able to have folders inside of folders. Meaning I can have a folder on the left bar that says christmas and press a drop down triangle that will let me have more folders under christmas such as the years (02, 03, 04, etc.). They would be known as categories. THIS IS A MUST IF iPHOTO IS UPDATED AT MWSF 2004.
They also need to make it faster, because I have a dual 1.25 g4 with 2 GB of ram and it RUNS SOOO SLOW compared to iTunes or any of the iAPPS. I understand that the program has to load tons of pictures but still, it should be just as fast as if you had a bunch of folders on your computer with pictures in them and viewed them in the finder. I HOPE APPLE DOES THIS!!!
