Along with the possible mod for alternative icon background color in XP under alert status I’ve accumulated a few more ideas.
In XP I think its possible to act on a click of the tray bubble. Perhaps on that click it could optionally open up to the alerts page?
I’ve got a “my” weather page on weather.com. If I were able to, I would have that open up on a double click of the icon. If Weather Watcher could optionally store a URL string for that would make it possible. It would be possible then to go to an entirely different weather service page.
