don't worry :)
I wrote this email before starting any code just to avoid writing
useless code ;)

I talked about gconf --> gsettings because Andrea told me that Unity
is moving from gconf to gsettings.
I don't know the details of their implementation. For example: do they
save the settings in the same format and locations? Can I save with
gconf and read with gsettings or are they two totally different
things? Just asking... to understand how they work.

It's pretty fine for me to start directly with gsettings.

I don't know if Unity-2D can or cannot use this.... are there any know
problems? Maybe we simply need a Qt binding?

nice! I will give a look to that code and I'll ask any question in a
different thread maybe.

perfect, I agree :)
