One issue with the GUI: after completing a conversion and saving the file, the "Select a file to convert" button is disabled. In order to convert another file, I need to exit the converter and start it again for the button to re-enable. Dealing with multiple files to convert, it does slow things down. (Using version 1.0.7.4)
Another GUI recommendation, but minor: have an option to set a default output path, so that the save puts it there rather than defaulting to the input path. As well, currently, after changing the save path, the save destination becomes the default for the input path. Keeping them separate improves workflow.
(The conversions themselves seem really quite good so far!)
