WeatherCatPad (WeatherCat for the iPad) version 2.3 is now available for download from the Apple App Store
Sylvester was replaced with the Twitter client in WeatherCat 3. And yes, there are plans for an RCP based desktop client, but it isn't in the immediate future. A 64 bit client is available as of V3.0.1 - see http://athena.trixology.com/index.php?topic=2755.0 for details.Cheers,Stu.
