Need some organizational tips.

Saturday my old fridge died. It was technically too big for the space it was in (which looks weird now that it's not completely occupied), and that meant I couldn't fully open the freezer, since it was a side-by-side and freezer door would bump the wall to my left when opening it.

Now I've got a top-mount freezer. The fridge section is OK, but I lost the many shelves and the storage bin of my old freezer :< just 1 shelf and the bottom, and 2 door things.
