One of my databases is dedicated to music with dozens of pages of sheet music. It would be nice if auto-scrolling was supported so that musicians and music students could set the beats-per-minute of the song and have it scroll (at the pace the song is played), through the several pages typical for many songs. It seems that this feature might also be useful for readers, who could set a words-per-minute, to help them improve their reading speed.

Onsong and Fourscore, in particular, are noteworthy
