Evan,
There are a few good reasons for having rudder trim available with the autopilot engaged in the Boeing.
For a start, it allows good engine out ability. Without being able to trim the rudder with the autopilot engaged, you would have to disconnect the a/p every time you changed the thrust setting. Not a good situation.
A rotary switch is used because there are multiple positions required on this particular lock design. Moving it to the overhead panel might be a smart call.
TeeVee,
The camera is a brilliant invention. As is having the door unlocked from the inside. If you seriously can't see why it the system is designed the way it is, then you're really not thinking hard enough. I'm certainly not going to go into the specifics of the setup, but its pretty clear to see why you need the door control on the inside.
I think yes, in hindsight, we can now see that having two switches that are of a rotate and hold design located close to each other is less than ideal. In fact they are the only two rotate and hold switches in the cockpit. I wouldn't be surprised to see them moved. But at the same time, the switches have been there for a very very long time, and this is the first time anyone has got it wrong. S$% happens sometimes.
