When I was using Stagetraxx3, I regularly used the wavefore to move through the song during editing.
The time counter immediately reflected where I was in the song (the exact time) and I could let it go in the exact place I needed. I notice in Stagetraxx4 that the time when draging the waveform is not shown until you release the slider. The original method was better where you could immediatly see where you were before you let the slider go.
