Due to the integration with S2U2, the relative low memory usage and stability with no2chems roms, I have kept SPB Weather as part of my Today screen with cLaunch as a default launcher.
Over the last few years I have tired of the standard skins and was surprised to see little on the SPB website. Here a couple of skins I located as a link from the SPB forum. The are mostly in Cab form, so copy to device and install. EXE files should be run from the desktop. They are immediately accessible from the skins tab on SPB weather.
