It shouldn't have an effect on battery life if the files don't have
replaygain tags, and IIUC the effect is incredibly minimal.

My understanding was that it cost 64k of RAM. That's not terribly
significant. It's not small, but for avoiding user confusion (forcing
them to look in two places, and reboot, to use a single setting, which
basically means the manual is required for them to figure this one out)
it's probably worth it. And isn't Pitch still adjustable with it on?

With a normal menu that updates live, this can be accomplished. Set the
value to 120% speed. Then move to 122% and when the beat matches cancel
out of the screen, immediately restoring it to 120%. In fact, this could
even give you finer control over beat matching than you have currently.

How would this remove that? I said two settings, "Pitch" (which would
change pitch without changing BPM) and "Speed" (which would change BPM
without changing pitch). If you need speed and pitch both changed, you
just change both of them.

They could (and possibly should) be.

"What you want when you're DJing" does not necessarily equate to "what
makes it easiest for users to understand and use." You don't actually
lose any functionality doing it as a proper menu, you free up some RAM
from the custom screen (possibly even significantly mitigating the cost
of making it always on, though that's unnecessary for this) and you make
it much easier for users to understand how to use, as well as being
easier to use on more targets.
