Lang8 Printer

In short, This is a kind of Lang-8 web browser for printing entries/corrections/comments to make your own learning book. I know only a few people in the world need this app, though.
A few years ago, I made a Lang-8 printer app for Windows.  If you simply print any corrections on Lang-8, the result would be very messy and collapsed as hell. With this app, you can print everything perfectly and consistently without redundant elements. You can even choose corrections or comments to print using the top-right floating area shown up on any entries.
