Can't do a screen shot from work . . . so I'll try this

:
Repertoire>>Set Lists>>
Now pick a set, any set

I use the split view with the numbered list on the left side, and Lyrics/chords on the right.
At this point depending on the settings, scrolling starts either automatically or manually with a tap on the document icon.
Double-tap the right side so the lyrics/chords fill the screen.
*Here* is where I'm thinking the addition of a document icon - a "pause/play button", if you will - to start/stop/suspend scrolling would be a big help at a minimal cost of screen "real estate".
If it were in the top right or bottom right corner, chances are it wouldn't be a distraction to those who don't need it.
