What about a widget that displays the current weather radar for my location?
Ernest John Simon commented
You can already accomplish a radar view by using the iFrame widget. Use the widget and then go to settings to enter a frame url (like below) of a radar map from your local weather channel website or from the "Current Radar" from intellicast.com. Example url: http://images.intellicast.com/WxImages/RadarLoop/spi_None_anim.gif
seconded. this would be great. Does Google honestly have anybody working on iChrome ? Seems like such an unfinished product with so much potential.
