My first attempt — Sounder Alerts. This widget uses the RSS feed that was created by my request to Sound Transit for an RSS feed that was limited to Sounder only (read story). So I decided to use my powers for good and create a OS X Dashboard widget called Sounder Alerts. This widget shows you the latest Sounder news. Click on the Sounder Icon in the widget and you browser will open to the Sounder Schedule.
Updated to version 1.1, got rid of time restriction on RSS feed, so no matter how old the news, you’ll see the latest.
