Here's Canti v1.84
New to version 1.84:
-Use original filenames
Canti uses -title, -manga_prefix, and a suffix (either auto sensed or size specified by -num_chars_keep_suffix) to form the output filenames.
The basic naming scheme is: [title]_-_[manga_prefix][suffix], for example: School_Rumble_-_Ch.1
@use_original_filenames allows you to use the original filenames of the source manga as the output filenames. This can be especially useful if your source files are not named in a way that auto sense suffix can handle (i.e. they don't end with the chapter or volume number).
This option supersedes the default of using auto sense suffix but can be disabled at runtime by specifying -num_chars_keep_suffix [integer]
This is set up in the .properties file.
Enjoy and let me know if it works for you
