When I am on AIR, I can do nothing. Gasmixes configuration is only for Nitrox.
It would be strange to me to configure gas mix of the AIR :)

That's also my point of view.

So either not Suunto divers are using libdivecomputer or they are not
diving with Nitrox :) or because default setting in subsurface is not
displaying O2 no one noticed it so far.
I also did not noticed it few months ago. Only now when playing with
different view settings.
