Widgets 4, now available for download for Windows or Mac OS X, also has a dock to keep the applications organized. The dock can be automatically hidden or can be attached to any side or corner of a user's monitor.
The new version also includes better programming tools for those who want to write their own widgets, a gallery widget to look for new widgets without using a Web browser and automatic updates when widgets are upgraded.
Also new is a Flickr widget that lets users view, upload and tag their images at the Yahoo photo-sharing site. And Yahoo updated the 21 widgets installed with the earlier version of the software.
