Do you know how else you can do that? by opening the door. We need to stop "innovating" features that absolutely no one needs, because clearly the result isn't a better product, just a messier, more complex one that is frequently over-engineered and under-supported.
The worst example might be windows in the doors, so you can look into them. Except you put stuff on the door shelf and block the view or you can't really see inside all too well. Plus now you have introduce thermal issues.
Only works for a neatly organized fridge. The way my kids cram everything into the fridge makes this feature worthless.
