That's the one I've tried a bit before, but haven't spent enough time to be comfortable with it. The crux of it for this project is that if I were making a UI I'd like to move the data validation in to that (and add some more sanity checking) with visual indications if there's a bad row or something looks off. Currently it just it yells at you and terminates if there's invalid data. So a UI rewrite would make it much friendlier to other users, but it'd be a time investment I can't justify over the "just don't give it bad data" strategy. The inputs and outputs are all handled manually so reliability isn't a huge focus as long as someone can poke around for a bit and make it work. Only user is me for now, so ¯\_(ツ)_/¯ # TODO: make it less shitty
