Martin,
This is a good start - you've obviously been working hard.
A lot of the most interesting stuff will come in the AOI section, so we'll still have to wait and see on that.
Two things that I immediately see are missing: 1)User's text color preference and 2)under weather, the user's hemisphere (northern or southern).
For the 99% of you wondering why #2, it's so the moon phase can be displayed accurately.
I also think it would be good if the units preference for weather was more specific, to accomodate different people's interests:
Temp: F,C
Wind Speed: mp/h,km/h,m/s,knots
Visibility: mi,km
Barometer: in,mm,hPa,kPa,mb
Precip:in,cm,mm
Cheers,
Will
