My first MeeGo application called DOF Calc today got in much better shape and actually is closer to being really usable.
First I've implemented landscape view, so it now looks correct when you rotate the device:
Another missing bit was configuration handling. I have not found something for simple configuration storing and everybody seems to suggest using Database API for that, so that's what I did as well.
For now only camera selection is persistent, for the others I have to consider whether it is really expected. Besides selection persistence, the database should allow to configure list of cameras/lenses/apertures, because I'm sure not everybody will like my predefined set :-). For now only camera definitions are stored in database and there is no interface yet for changing that.
