Is it possible to mark two incidents and have the time between them displayed in mS?
Another thing: I know it is possible to see a stereo track in Audio Edit window, sometimes it could be nice if you could select two specific mono tracks and have them displayed just like you have a stereo track. This way you could examine and maybe edit delay issues!

merge two mono to stereo (Track menu), then look at it .... don't forget to check the box for which side you want to edit.

That's exactly how I did it :-)
What about my first question about being able to tell how many milliseconds there is between two incidents?
