Gnome Do rules. One of my favorite plug-ins is the del.icio.us Tag Search, which makes all of your Delicious bookmarks and tags searchable and launchable. Install the plug-in from the preferences menu by summoning Do and clicking the arrow in the upper right-hand corner. Select "Community Plug-ins" or "All Plug-ins" from the drop-down to add the plug-in and then hit configure to enter your Delicious credentials.Once you're all set, you can type any tag you've used in Delicious, or any word that appears in the title of a bookmark. Hit the down arrow button to browse entries and the right arrow button to browse inside tags. Use a tag like "quicklaunch" to get to your favorite sites quickly without the mouse.
