Now as the title suggest this is nothing that i cant live with-out, but would be a nice addition. I would like it if you could adjust the speed of the slide show mode. Or perhaps even a way to create a time-line for your own preferances; to view each picture for a specific amount of time. Anywhere from one to ten seconds per pic (or less). Just a thought. Really im just intersted in a the speed of the slide show.

p.s. anyone reading this feel free to add to this list of "Little Things", its not just about the slideshows speed.

VenenoCY suggested something along these lines on the first Photosynth help forum a while back. He got some responses from David Gedye, if you're interested.
