Not sure if I will include it in the end, but as the option of switching between "full" and "alpha" has been requested several times, I would be quite interested in how you would have implemented that.
Otherwise, disabling the "double shift = caps" function seems like a very good idea and a good compromise between both worlds. First time I accidentally triggered that mode, it drove me nuts, and I was pretty harsh toward that poor, innocent caps key ... 😳
