I definitely suggest checking the folding out - I find it doesn't make a difference in terms of how much I can fit in the drawers, but it does make everything visible, which is a huge thing!

So far, with the bag-emptying, I haven't forgotten anything when leaving the house, though I'm sure it'll happen someday. It probably helps that I keep the essentials together: I have part of a drawer designated for my car keys, wallet, and registration; they're all next to each other.
