• MultiViewBar is now free and included in the library, source and all.
• OneClick - non-visual control that helps the page developer avoid the dreaded double-button-click
• Polling - controls and framework for showing users simple web polls. Uses a provider framework, with built-in providers for Access and Sql Server.

• QueryCall - Component which maps querystring parameters to methods in the codebehind
