Moving/movable playback position indicator for SER files in the high speed test camera

[Borodog]

Hi. I'd like a slider in the high speed test camera that indicates the position of the "playback head" in the recording that can be grabbed and moved to "scrub through" the recording, if you are familiar with the term. A pause/play button would also be nice.

I have no idea how hard or easy these features would be to implement. :O)

Thanks for your time and consideration.
