I might even have a drop cord outlet hanging down in the center of the shop.
Definitely do that. A retractable cord that can be set at different elevations depending on where you're working would be awesome.
When I first started working on my truck, I had an extension cord laying on the floor and had to bend down and pick it up every time I needed to change tools. I was getting too old for that, so finally ran a cord down from the ceiling. MUCH nicer just reaching over to plug things in as opposed to bending down to the floor.
