Widget Manager manages your widgets. Not really. Actually YOU manage your widgets via your widgets sub-tab. What this lets you do is copy the widget config from a blog you pick as your "mother blog" to any and all other blogs. Useful if you want the same, or basically the same widget selection on all your blogs is the thing. Like, copy the "mother" config over to a new blog, then do minor tweaks to make the new blog be exactly what it needs to be.
This plugin will automatically make a table of contents for a post by looking for the h1 to h6 tags in its content.

This plugin creates a toolbar that allows the blogger to easily include a Creative Commons license on each post. The license can be a default license or specifically selected for each post, or not included at all.
