I am sure Apple has worked on making the individual applications more multi-threaded than they already are, but my wants from the individual applications are:
iPhoto
iWeb
iMovie
iTunes
iPhoto
- have multiple libraries or able to change libraries from within iPhoto instead of having to hold the option button while iPhoto starts when you want a different library
- option to password protect each library
- ability to cut/copy/paste or drag-and-drop between film rolls even when a search is used.
iWeb
- able to add a link to the navigation menu that can link to a page that is not an iWeb template.
- able to publish directly to non .mac web site.
iMovie
- make it so we can copy clips so we can get more than one use out of each one.
- improve the timeline editing to support 2 video and 3 audio tracks.
iTunes
- Get music videos, video podcasts, TV Shows, and movies to play sound through speakers connected to the AirPort Express with AirTunes
