I used the "ordinary" Lithium reader and was very satisfied from its many options, ease of use and appearance. I have purchased the Pro version only as a tribute to the developer for giving us, free of charge and Ads, such a good App. Also the developer is quick to answer any question from the users.

purchased the pro hoping maybe itd let me read txt files. looks like only the epub files i have are readable, not the txt files. still, pretty straight forward simple epub reader. not expensive so i dont mind supporting small developers. wish they read txt files though.

I'm loving it so far, but I'm hoping there's an option/shortcut to access the chapters list rather than having to click the options menu and then clicking contents. It would also be nice to be able to customize the main (white bg) theme as the other themes seem to not display any colors in the epubs I'm reading.
