UPDATE 15 April, 2011:

PizazzWP plugin is no longer available as it now comes  built-in to each of the other plugins.

 

PizazzWP also includes a few useful shortcodes for:

MailTo shortcode: Obfuscates email addresses.

Related Posts shortcode: Shows related posts.

WebSnap shortcode: Show a snaphot of a webpage.

Donate shortcode: Adds a PayPal donate link.

Private Content shortcode Makes a block of content only readable by logged in users

Floating Buttons

Furthermore, PizazzWP lets you very easily create up to three “floating” buttons that affix to the side of the browser for things like contact, feedback, follow etc.

PizazzWP works with any WordPress theme!
