For those unfamiliar with Konfab widgets, check out the official website here. Widgets are essentially mini applications. Some widgets expand on the functionality of applications.

Update: Thanks to Andrew and Jeffrey for pointing out that users who recently purchased Konfabulator will receive a refund. I guess I overlooked that line in the Yahoo article.
Update: “Yahoo Widgets” are now free. Download your copy for OSX and Windows here.
