Maybe we should put all of the "RAM saving" options together under System >

The current UI nudges the pitch up/down only while you hold a the key down,
making it really easy to use. I really can't see that a menu UI would work
so well.

You'd need to calculate the corresponding percentage, and you can't adjust
both parameters at the same time (e.g.. you'd increase pitch, then decrease
speed, rather than doing both at exactly the same time as you currently can)

I agree that we should be making it easier to use, but I disagree strongly
that a menu would make for a easier-to-use UI here. (I can only speak for
button-based use, I've no experience with Rockbox on a scrollwheel or
touchscreen - that might be very relevant to our disagreement.)

Certainly, defaulting to having Timestretch enabled would improve usability,
but I don't know if other developers would accept the RAM impact (when
discussed on IRC way back when, it seemed timestretch wouldn't be acceptable
for committing if it gave a compulsory RAM loss).
