    This is amazing! Would love to see this actually get produced in the future as the functionality of a modular keyboard like this is absolutely incredible! As a content creator, I especially love the idea of the video editing module as that would be such a productive tool to use (though I'd prefer to see the screen relocated at the top of the keyboard instead of the bottom if possible, and potentially even moveable so it could somehow be able to move into a vertical position to be more visible in the line of sight without looking too far down). Very impressive that you created this entirely on your own!
