How to install a widget via a plugin
Sidebar Manager is not just a plugin, it is a platform. One of the core principals of Sidebar Manager is to provide other plugin developers with a tool they can leverage in delivering cool functionality to their users. For example, suppose you are Tim Appnel. You could have your Feeds.App plugin install an RSS feed widget into Movable Type. Users could then add that widget to their sidebar in a click of a button, using the Sidebar Manager plugin and platform.
