You, DopedAngel, deserve some kind of award! And reward! Not only did CoolReader solve all of my problems (and, as you said, give me lots of cool options to play with ^^), now I don't have to deal with the hassle of converting my entire eLibrary!
[dances around like an idiot; nook in hand]
You have my sincere thanks! I'd given up trying to find an app that would take care of reading after ruling out the Kindle, Moon, Nook, and a few other android reading apps didn't provide a satisfactory experience. CoolReader is far and away the best I've used.
Thank you! Thank you!
And thanks to everyone else who also offered to help me find suitable solutions. I appreciate everyone's input. =)
