Hey there Honf,
great little app you wrote, thanks a bunch!
Just some quick questions and suggestions:
1) At this point Mangize doesn't support archives, does it? Because I get an empty XYZ_Processed folder when trying to convert zipped chapters.
2) When opening a file/folder it would be nice to remember the last position.
3) An option to convert pngs to jpegs would be nice - to save some additional space. Or is the output image quality of the jpegs substantially inferior to png?
regards and keep up the good work!
