I'm wondering if a feature I have wanted for a long is implemented in iPhoto 5. I would like to be able to change the file name in the library to match Title assigned in iPhoto without having to export the photo and re-import it. The current and past versions lack this feature.
The other thing I've been hoping for is the ability to burn simple photo CDs (just the images) from within iPhoto. Currently, burning from within iPhoto creates an iPhoto archive that includes all of Apple's metadata files and thumbnails. To make a simple photo CD now you must export to the CD and burn it in the Finder.
By the way, I think you may have misunderstood the "blurring" issue brought up earlier. In iPhoto 4, when you enter edit mode it actually goes through three transformations if photo cannot be displayed at full resolution. When you hit edit, you get blurred-picture->sharp-picture->anti-aliased-picture. It sounds like the new method eliminates the transitional blurring during the process, but I think the guy was interested in the last step, i.e. does iPhoto still apply anti-aliasing to all photos in edit mode that can't be displayed at full resolution.
Thanks for the great article. Very informative.
