Hello guys, not sure if my app is going to be helpful to any of you, but I came to say thanks for the wonderful lib you have here. No matter if it's a bit abandoned, it's still helpful!
Ok, as for my reader, it's opensource, it supports vertical and horizontal layouts, unicode text (UTF-8). Also, you don't have to bother converting books as it supports the most basic format - txt. Actually, it's so basic it treats every newline symbol as a paragraph end, mind that there're eBooks out there that have newlines that don't mean anything.
