Thanks for the suggestion! Perhaps a front end could be created for the tool, but I haven't put much thought into it since other features seem to be more important to people (Ie. Machine Language Translation of subtitle files, etc). In the meantime, if you need help with the command line, let me know and I'd be happy to assist you. Because most of this is done automatically, the commands you need are usually extremely simple! (^_^);
Edit: Patreon requests are always prioritized at the top of my backlog, so if your really serious about getting a GUI/frontend solution, perhaps consider subscribing to my Patreon. I like to try and help everyone, but since my time is rather limited, I need to focus my effort where it will benifit the project the most.
