Yahoo! released version 4.0 of its popular widget program yesterday.  I am really impressed!  It now sports a widget dock for easy access to your widgets which you can anchor to any side of your desktop.  It also features a Yahoo! Widget Gallery widget that allows you to find and download more widgets for your desktop.  As always you can hit F8 and your widgets will instantly be in front of all other windows so that you can view them easily.  I am really happy about this release and I have now completely switched from Google Desktop.  Yahoo! Widget Engine is the best out there now in my opinion.  To give this sleek and fun program a whirl, visit http://widgets.yahoo.com/.  Have fun widgetizing your desktop!
