The upper cabinet design has changed somewhat. After reviewing with my wife Jennifer, we decided to limit the left side to two shelves. The shelf components are built and glue is drying. They will go in tomorrow. To keep the microwave from walking while traveling, I removed the bottom two cover screws and will be replacing them with longer ones that will run through the lower 3/4" runner at the bottom of the cabinet wall.
