Great Work!
Unfortunately I'm using the mobipocket reader on my Iliad right now (if I even have time to read at all...) and there is no such wonder-package for that one...YET...
Maybe we'll get our reflash option soon and then somebody will create a powersaving system that benefits all apps.
But anyway...I'll install this package as soon as I have time and might even go back to the cumbersome PDF format just so that I can experience this great bunch of cool stuff from our dearly beloved mobileread.com Iliad devs...
