...Wanted the convenience and sleek look, and I'm really happy with how it turned out...
Looks fantastic, and money can be saved by using the circuit breaker panel as the cutoff switch.
Here is a photo of my install between the single and dual garage door. The required cutoff switch does add expense. This is one reason I assume Tesla Motors encourages the 40 or 48 amp charger at purchase time, to keep EVSE installation costs down. IMHO, the Model S and X deserve the highest 80 or 72 amp charge capability in the car. Wall Connector owners only need to wire the EVSE with what they need now, but should consider optimizing the install if they might need to charge faster at home in the future.
I placed a color tape around the wire where it is at the upper left of the cutoff switch. I can grasp the charge handle and wire at the color tape position in one grasp with two hands. It's easy to remove and position the cable on the garage floor behind the rear of the vehicle parked at the larger door on the right. Returning the cable to the wall is quick, the color tape shows where to grab and place the wire, no winding at any time. It's all in a single loop. The coil at the bottom is extra cable that I do not use each day. Fast placement and repeatable. Done in a few seconds.
Not sure why the switch is off, I normally leave it on. Every install is different, so enjoy your own time-saving positioning of the wire from the wall to the car and back again. You will be much happier than having to wind the cable each time into a small coil.
