But there's no inherent reason that you need to shift by rotating a lever. It would appear that you could make a lighter, simpler to use group by eliminating the shifting levers all together, and just going to buttons, like the auxillary shift points they already have.

I think the interface of Di2 can be improved a lot, once designers are freed from needing to make it mimic mechanical groups.
