Great app! Some suggestions.

This app is the best I ever used for comic book reading. Everything is so nice and good. Especially trimming option is fantastic!!
However, I wish some parts to be improved.
First, app cannot read the file when names of image files are encoded with some minor languages format such as Korean, Chinese, and Russian.
Second, this app only support dropbox. I hope there are more options. Especially FTP server and google drive.
Last, only can read when image files are zipped in one file. I hope this app can read folders too.
