If you're going to think about check boxes, we should really see a radio button option as well.

With the future of Silverlight looking bleak, I am closely watching the development of this new UI/Framework. The Telerik Silverlight RadRichTextBox supports a lot of key features that MS Word has (i.e. Advanced formatting and tab stops). 

Will tab stops be supported in the first itiration of this control? This feature is extremely important to me for a large part of my user base will be also using iPad when not in the office and since Silverlilght is not supported on iPads, I am going to have to start redesigning a lot of are site since the core of it is Silverlight.

This is an essential for us, so I'm glad to see it planned. I would be concerned that the Kendo version of the Editor not be limited in capability like the editor from the ASP.NET MVC extensions. A **document manager** is essential in addition to an image manager. I've used the web forms RadEditor in the past and as we make a transition to ASP.NET MVC, having an Editor as close in capability to the web forms RadEditor is critical. Please give us something with full capabilities!
