4 photos: There's all kinds of ways to put storage to work; this one uses a pull-out can storage attached to the door (and support with the tracks secured to the base floor, of course!) The top rack is adjustable and can be relocated higher up if needs serve.

We open up the top drawer in our second image, and slide out the door in our third image.

We get a good look from the side in our fourth image; note the hooks where the tray can be secured at a higher level.
