Add wipe offset

Karaoke lyrics typically start wiping 50-100 ms before the person should be singing the lyric, due to human reaction time. This aids singer timing, especially if the singer doesn’t know the song by heart.

I’ve noticed that the auto-sync tends to start lines late, so I have to adjust every word to wipe earlier. Even if the wipes started perfectly on time, they would still need to be adjusted.

KBS has an offset feature that automatically will wipe earlier depending on that setting when the final track is rendered.

KBS also has the ability to select all wipes and move them to earlier or later.

Either of those functions would be suitable. I think an “offset” input that can manipulate all the wipes at once in realtime would be ideal.
