For Weather:
Open up Clock.ini and change the zip code to your zip code. Simple enough. To change to celsius, change the ImperialorMetric value to "m". The city location is simply a label, not a result from the weather feed, so you must change the CityName variable to your location.

Note: There are no quick launch icons in this release. A future release will contain quick launch icons although if you still wish to have the quick launch icons sooner, I will try and add them ASAP.

That's about it. Enjoy and please report any errors to me!
