A Scratch library for a better mouse interface. Drag to move the red grid. Click and drag to move the cyan grid. Press the button. It doesn't do anything in the demo but it won't interfere with moving the grids. Modin v1 can sense: drags click drags button support Modin is short for modern interface Note that the button itself is not part of modin and is in fact very crudely put together. A modern button is typically activated upon release.
