Perhaps the original owner did the same as I did:
The switches in the "Convenience Center" were less than convenient, so I added a pair that were easy to access. I purchased the switches from the large online retailer that are identical to the existing switches.
Additionally, I added a switch for the light over the sink:
I should replace the (now unused) switches with blank-out covers.
Perhaps the factory installed optional switches upon request, but the original switches were left in the panel...
