The reader's nice, that's for sure. My books are also organized nicely, so the directory navigator is handy. (Easy to do because I have a handful of books. But 8000 books. Wow! That must have taken forever to organize.)

I'm going to take a look around the lua sources to see if there's any easy tweaks for the Aura. I'm hoping someone with knowledge on the hardware end will figure out the light and sleep mode.
