I think that such a big change needs time to be introduced.
And unless anyone comes up with enough fundings to pay the whole development
at once we need a way to allow for an incremental approach. I'm basically
just trying to find a compromise allowing for further development to happen
w/out it being relegated in a PR which would be harder to share among
developers or test on the field.

Having the functionality available, but hidden in a preference, would allow
more consequences to be spotted. I've seen many reports taking place which
took over 2 weeks to be found. These issues would not be found if the code
was not in master for people to play with.

The rotation functionality might be reported as not being complete in
the GUI allowing for enabling it.

Of course I'd prefer having all things working, but I just could not
raise enough funding for everything, and delegating the work done so
far in a PR might make it hard for anyone else (not just me) to find
more to build upon what we have now.
