Plugins

TiddlyWiki can be extended by installing plugins that implement a wide variety of features (including Macros, themes or tweaks).

Community member Dave Gifford oversees an extensive catalogue of available plugins at TiddlyVault, and Eric Shulman maintains his own impressive collection of plugins at TiddlyTools. More recently, Saq Imtiaz has built a service which lists plugins from all around the web in a single place, at plugins.tiddlywiki.org

When you've chosen the plugin you'd like to import, follow the directions in ImportTiddlers (just make sure to tag the plugin systemConfig).
