Version 2.0:
Auto jump to last thing you read -> HELL YEAH!
"Underflow" to previous chapter -> HEL... oops, it always jumps to the first page of the previous chapter. Is there any way for you to make it jump to the last page of the previous chapter (like browsing a real comic)? It probably makes it harder as every chapter could have a different length.
Oh, and btw, you're still programming in WAF ... didn't you want to change to Java
