I'm wondering if you can elaborate a bit on what you think what the
point for cockpit usability roughly is?

My personal 'must-have' requirements are that, assuming you entered the
task before taking a launch:

- if its a good day and you complete the task, you shouldn't have had
to touch the system during the flight, i.e. you get task start and
finish notifications, the display zooms in as you approach a turnpoint,
there is a beep and the next TP is selected as soon as you have a point
in the sector and the display zooms out again.

- if you need to skip a TP, abandon the task and head home, or get a
course for the nearest landable field, these should all be doable
without messing about with menus, etc.

- the map shouldn't be cluttered with airspace unless there's a
possibility you'll enter it.

That's my definition and please note that in the UK we seldom if ever
need to change tasks after take-off.
