Over the years I have put together many modules, plugins, and enhancements into Sitefinity 3 to create a new flavor. I felt it would be a good time to release them. Some features thankfully made it to version 4, others I plan on porting. Check out the pages constructed out of the box with what I call Sitefinity 3 Ultimate Suite!
-Google Analytics integration
-Events, news, and blog modules enhancements
-Ordering capability with Paypal integration
-Post events, news, and blogs to Facebook and Twitter
-Rotators for events, news, blogs, lists, and images
-Web-based CSS editor
-Create pure CSS menus
-Friendly error messages with admin notification
-Configuration management interface
-...and so much more!
I would be glad to hear what you think and if you have any interesting add-ons.
