Friday Question: Useful Dashboard Widgets?

After that little rant about useless Dashboard widgets, I feel the need to redress the balance. My problem with widgets is that most seem fall into 3 categories:

  1. Searching widgets that are no more convenient than just searching in a browser (especially when most browsers have some way of adding search engines to the default google bar)
  2. Widgets that display information from other apps – viewing iCal events, or unread mail.
  3. Widgets that are just a way of viewing a single RSS feed.

Apart from the default calculator, these are the two that I’ve found worthwhile:

Capture (More than what you can do with keystrokes, it lets you choose filetypes, scale and saving destination)

Google Maps (the one widget that I’ve found to be more convenient than going to the browser)

There must be some useful widgets out there, but maybe there are some little gems that you’ve discovered? Show me your widgets!
