That said, I don't love the default design choices here -- colors and "polish." I'm not a professionally trained designer, but I've hand rolled enough software that users eventually complained about to sense when something "feels off" compared to what a really good designer creates with a background in color theory, information density, gradient shadings etc.
If the author is here, have you considered leveraging the aesthetics from other FOSS projects like bulma or tailwind, or collaborating with a professional designer? I know jgthms is sometimes on this site.
