Wow, I made same GUI in react and got 0 stars :(, but I would still rather use mine since it is more performant, has less css bloat (don't need css in middleware), and has more useful functionality and features which I need such as precise range dragging, infinite menus, anchor snapping to edges of screen, some realtime line/bar charts, and a more slim ui.
