Hi Faheem.
Ok. I understand your request. Now fonts for presets is hardcoded in code. I will think about including it in configuration. You can switch to legacy mode using parameter 'mode' in gconf.(unload omweather and set to '1' this parameter) And try to tune external view of OMWeather.

Great app, couldn't ask for better. Could only ask for developers to put apps of this usefulness and stability.
