From some internal discussion, it'd be nice if Captain mode includes the current "Download and Apply" button in version chooser, and Pirate mode then splits them out into separate buttons...

Thinking about bluerobotics/cockpit#1427, and the likelihood of future live sharing situations, it may make sense to also have a mode for "Passenger", stripped back from "Deckhand" to view-only access. That...

- Unsure of the relation to #2660

Still intending to do some corrections to the compass calibration page, and possibly some of the other vehicle setup pages too.

@Williangalvani could you check the compass updates? :-) I'm unsure whether the log-based calibration description is too long, or whether it's ok given the content it's currently covering.

Also raised in [this forum post](https://discuss.bluerobotics.com/t/trying-to-connect-rpi-to-pixhawk-4-through-telem-1-2-port/14131).

This is more important than we seem to have realised, because some firmwares apparently [correlate USB power with being on the bench](https://ardupilot.org/copter/docs/common-telemetry-port-setup.html#:~:text=the%20flight%20code%20assumes%20that%20if%20it%20is%20receiving%20power%20through%20this%20port%20that%20it%20is%20on%20the%20bench), and disable some failsafes as a result.

Some comments [here](https://discuss.bluerobotics.com/t/trying-to-connect-rpi-to-pixhawk-4-through-telem-1-2-port/14131/9) on a recommended approach for adding a serial override option.

Could potentially be handled as part of #2005
