Future firmware suggestions

Here’s another “enhancement”:  Evidently, only files in the Audible, Audiobooks or Padcasts folders are treated as audiobooks.  In Settings, you can change the speed of audiobook playback, but that doesn’t effect mp3 files in the root of the SD card.  Why not treat all mp3 files the same and permit slow, normal or fast playback regardless of which folder (including root or Music) they’re in?
