Add 1] .Connect the folding mirrors to the ignition switch to reduce fumbling around on the dashboard for the actuating button[difficult at night].
This needs to be clever, such as to only unfold the mirrors whn moving forwards at more than 10mpg. Some people need to fold the mirrors for parking in a confined space so it's not a good idea to automatically unfold when the iginition is turned on.
Well for this issue Honda could use the mirror switch from CR-V (which is illuminated) 35190-SWA-J02, I'll help with the night issues.
On our Jazz/Fit GE it's possible to make this modification, you just need to get the ilumination and earth signals.
It'll look like this:

It's also possible to integrate the opening and closing of the mirrors with the door locks with an aditional module (Honda Access Japan). This is clever because if you folded using the button it won't open with the locks.
To sum up, honda have the bits but don't use them in every car.
