Looks great and adding it to the door makes a lot of sense.
I notice in the first bay you still have the drawer unit hanging from the bay ceiling. As long as you are improving the bays consider moving the drawers to the joey bed so when you open the drawers you can actually see what is in them.
Notice I took the chairs and chair pockets off the bay door so I could move the bay drawers more forward to provide needed depth to the bay on the other side. Note the chairs are now under the drawer unit.
Behind the drawer unit and tool box I have wash bucket, towels, and kits such as drill, screwdriver, computer reader, jumper cables, etc.
