Small update. If you downloaded v1.2 you can just overwrite the .jar and .properties file with these. No need to reprocess your manga.
And if you already processed your manga but now want to use auto-binding, just turn on auto-binding and run the program again... it won't waste time reprocessing the manga, it will go straight to the binding.
New to version 1.3:
Same as binding, except you don't create a bind file. Instead, you just specify a single size for all bindings (for example, all bindings could have 10 folders in them).
This is set up in the .properties file.
