I don't remember that this was what we intended, but as you say... plausible for sure.

That's always painful and risks getting out of sync.
Doing multiple true/false arguments is far easier when calling from QML

Yes, ultimately that's the correct answer. It's a frequently requested feature, it makes
sense to have, and it allows us to use the same, consistent behavior in both places
to have the dive computer that was downloaded first be the first in the list.

I KNOW that this will lead to the request to be able to reorder dive computers on
mobile, but so be it.
