I will agree on the sun shades. I would much prefer being able to close the back and leave the front open.
As to the one-touch partial-closing of the BAMR, I'm not worrying about it. It opens all the way when I push the button. If it closes 3/4 of the way when I push it again, so be it. I actually have left it open that small bit at times too.
Bigger things to sweat my friend.
