Add in timed sounds, animations, transitions, etc.

Well, for example, as you're browsing through a very complicated flow chart, I'd like for certain animations to pop up saying: "you are now looking at section B...". Of course, I want all of these blurbs to go away when you're zoomed out, because there would be too much clutter and confusion otherwise.

Interface ideas for setting timing?... I suggest you utilize the right mouse click for advanced object settings, timing, etc.

I'm interested in this too! I want to do a graduation program for 8th graders and show projects and pics of the kids over time. I have some snippets of video (plays, performances etc) that I'd like to include.
My idea would be to activate the animation/vide when you zoom to it. So you'd be moving around in the presentation, zoom to an uimage - and have it go live with motion and sound.

How about a dialog that would appear when you click a path node, and the user could fill in the desired number of seconds to next node?
