Fernsehen gives you easy access to the german TV program provided by TVToday. See what's currently on, look for upcoming shows, search for movies starring your favourite actor or read a short description about a movie you're not yet sure to watch. And since the widget caches all the data, you can even do this offline.
But there is more. Simply click the alarm clock icon next to a show and you'll be reminded shortly before it begins; if you wish, you can have your alerts delivered by Growl. Switch the channel of your Elgato EyeTV, Formac`s Watchandgo, Equinux' TheTube or Zattoo, or program it to record a desired show with one click.
There are lots of preferences. Group the channels as you like or create filters and the widget will remind you automagically of your favourite shows. Change the size of the widget and accomodate the fontsize, or click the titlebar to collapse the whole widget (Try holding [shift] while you do that...).
