This is a great project, but material design was the worst thing that Google invented and implemented. Completely tasteless, visually unappealing. Would be nice to see such a project with anything else than material design.
And worth noting that this mostly implements the newer version of material design (M3). However, M3 was a lot more focused on shapes besides just circles and rectangles, but they don’t seem to have quite gotten that here
It's definitely slightly outdated, though. M3 Expressive for instance, the default text field has the textbox labels stay within the textbox, not move into the border.
