The ability to lock a slide’s timings is useful. However the ability to lock the start, and or end of a slide to the timeline would be valuable. Say I have 50 slides with two audio files for a 6 minute show. The first audio file ends at the 3 minute mark and the second begins. If I had the ability to lock the start of slide 26 to the 3 minute mark, I could then play around with the timings for slides 1 through 25 without moving slides 26 through 50 on the timeline. This way one change early in the timeline will not cascade down the timeline to slides associated with other audio files. It would allow you to sync your slides to your audio files as you develop your show, and if later you wanted to changes timings in one segment, you would not have to worry about it throwing the rest of you show timings off.
Another option would be to lock a slide to a portion of an audio file, that way if you move the start of that slide on the timeline the audio file will follow and that slide as well as the ones that follow will stay in sync with music.
Just a thougth from a computer geek, but a PSP noob.
