Expanding on the switch fuse-blowing issue. MCD assumes that all normal people will just install one switch to operate the shade. Since I do not fit that category, I decided 2 switches would be better. MCD's wiring scheme has the switch directly supplying power to the shade motor so adding a second switch can allow for a short circuit if the two switches are activated for opposite shade travel at the same time. Fixing this requires the 2 switches to each have their own up and down relay (total of 4) that have "back contacts" that when the relay is activated to run the shade, it also breaks the circuit to the other switch's opposite direction relay preventing it from operating and avoiding the short circuit scenario. Since it's just the two of us, the rule will be 'one shade operator at a time'. The worst that can happen is the fuse gets blown and the fuse holder is easy to access and I have spare fuses!
