Looks good.
However.
Sometimes, in that configuration, the disposal can pump waste water right across into the other sink drain, and it can shoot up from the drain or partially fill the sink.
If that happens, changes can be made.
The dishwasher stink is because food particles can decompose in the drain line.
Then they drain into the disposal, mixed with warm water, which lifts that stink right out of the disposal opening.
You can try running the dishwasher more often.
That AAV isn't helping when that disposal drain is pressurizing the piping contents. Not saying you should change it but I bet if it was a piped vent, it would be less apt to blow it up the other sink basin.
But if you ever do re-pipe things, I would suggest mounting that AAV as high as possible, while leaving enough clearance to allow it to be replaced, if need be.
Oh! Okay. My thought was that the AAV close's when subjected to a little pressure, while the piped vent is open to flow in either direction.I added the AAV per advice of a plumber. This is already a properly vented drain with an open roof vent.

Another thought that just came to mind is the fact that those 2 basin drains join together in a tee of the same size and doesn't increase in size until after the tee. I would think increasing the tee size would help the combined flows and/or some of that restriction going down.
Only thing i see is the AAV looks a tad low to my eyes
If you were to cut the pipe below the AAV.
then add a 2'' tee. with a CO
then reinstall the AAV on top of that'
I think you will thank me if you ever have to snake that drain.
