A few things I would like to get added:
Pilot seats - Like the attachable dummy, but in a seat. Camera is dummy's head.
Buttons - Switches and knobs. with Dummy PoV, you can look and activate switches, select and drag to turn knobs.
Windows - So I can see out of my craft, unless I'm in a super cool high tech sub. Then I'll need some cool monitors, maybe some radar too.
Logic - In the form of logic gates, computers. These would work with buttons and switches. Timers and sensors could be useful.
Welding - Already suggested this, just a way to connect parts without using the connection points. Could work as a wiring tool for the logic idea.
I mean, new cockpit modules are coming, and I'm sure those along with the command pod will have first-person view settings just like SP.
