why this limitation? IIUC if the user seeks far before the intro, then this will just skip the fade, does this make sense? Why would this be desirable?

Imagine a live recording with some introduction words.
The user probably has marked an intro when the music starts. Without this change and with a previous track without an outro the loooong intro time is used for fading if it is cued at 0:00. This is likely not desired. Now the transition time from the spin box is used in this case.

The other use case is the part of the bug fix. If the track is cued at intro start and the user touches the jog for a small seek. The intro is still used.

Makes sense I guess. I just worry about the complexity this introduces. AutoDJ is already quite unpredictable IMO and this doesn't make it any better.

It's also a drop in the bucket, so who cares...
