Well no, you'd build a page of 200 names and cache that. When you exhaust
the first 200 names, then you build the second page. You'll get a spin
whenever you cross page boundaries. But like I said, that's better than not
displaying more than a page at all...

But I appreciate why we made the compromise to begin with... it's the
simplest solution.

And then what? Read the each folder name as we display them? Spinning up the
drive every time we scroll the display? Whichever way you go, it becomes an
ugly kludge with boring side effects.

The fact is, we are constantly making compromises between battery life and
player performance. That's why we have to introduce limits such as max 200
files per dir and max 10000 files per playlist.
We could very well support 5000 files per dir, but then we'd get less
battery life. And since nobody else has ever objected to the 200 limit,
we've found it appears to be a good compromise.

However, we are not pigheaded. If you come up with a clever algorithm we've
overlooked, we will definitely take your patches into consideration.

Until then, may I suggest you simply organize your mp3 collection? :-)
