Huh. Just a thought, is there a point in the "whip" of the chain there where the overall curve of the lines approaches the same shape you get from i^i^i^i^i^i...(etc)?
Minor nitpick: When hovering over the slide buttons, the mouse changes to a hand symbol which indicates that dragging should be possible, but it is not. Maybe if it acts like a checkbox, it should look like a checkbox?
They are draggable, but it will not register as a transition unless the mouse button is released while still hovering over the slide button. It is effectively just a checkbox.
