question for the electricians

Yep, Depending on when the house was wired, what codes were in place, The disposal may or may not be a separate breaker. Dishwashers, microwaves, refrigerators, etc.., are on separate breaker circuits in modern construction code. I'm not exactly sure about disposals today. My disposal is on the dishwasher circuit. Two switches there.
Adding a live outlet is close to the sink and water though. GFIC breaker is a must, and you may already have that too.
