💡 RFC: An auto scroll feature that works from timestamps in the chordpro

[isaiahdahl]

Background & Motivation

I want the chart to auto scroll, but accurately. Not just guess the speed of the auto scroll and hope it's right and then have to adjust it half way through the song.

This could be really useful for a large lyric rendering. Where maybe only a verse and chorus is visible on a page at a time.

Possible solutions

meta for song length, easily grabbed from the mp3.

Add a few directives along the song with the time stamp of where the song should be at that point.

Auto-scroll could figure it out from there.
