Component: Sidebar Widgets Plugin, version 1.0.20060711
Patch: SidebarWidgets_no-title-means-no-header_plus_rem-wordpress.com-meta-link.patch
Apply this patch in the /wp-content/plugins/widgets/ directory.
Description: This patch does 2 things:
1. It affects the Text widgets, removing the empty header, (<h2 class="widgettitle">&nbsp;</h2>), that is added to a text widget that has no title. The empty header is an annoyance because it adds an empty space where no space is needed.
2. It affects the Meta widget, removing the link to wordpress.com. The link is unnecessary.

Component: WordPress core, version 2.1
Patch: WordPress-2.1_show_blogroll_descriptions.patch
Apply this patch in the /wp-includes/ directory.
Description: The default behaviour for the blogroll links display in WordPress 2.1, (using the Links widget of Sidebar Widgets Plugin, version 1.0.20060711), is to not show the link descriptions, which is the opposite behaviour of previous versions of WordPress. This patch reverses that, making showing the descriptions the default. It patches the _walk_bookmarks function in the file /wp-includes/bookmark-template.php. (There is no way to change the default behaviour, with or without this patch.)
