Recycle slice number visible during playback
when the play head rolls from slice to slice there should be a numeric text label showing it.
the lower right part of the window has
106 slices, 2m, 27.89 s / 27.1 MB
if it would read
55 of 106 slices, 2m, 27.89 s / 27.1 MB
updating as it goes along.
perhaps if you click on the text a pop up menu to navigate to a specific slice
