Thank you for your suggestions.
We do have a visual style builder for the RadControls from the ASP.NET AJAX suite, which allows you to build skins for them. Since Sitefinity ships with the complete suite, you can create skins for them in the style builder and then use the controls in your sites. As for building themes and templates visually we have been thinking about this before and and came to the conclusion that this is something very nice to get incorporated in Sitefinity.
For building skins for the RadControls, please take a look at the Telerik Visual Style Builder
. It is a free on-line tool and you will not need to install it.
