We would love a couple of Lightswitch HTML controls.  Not expecting the full stack.  

Even if you could just help us understand how to integrate Kendo UI more easily that would help too.  It's a great framework or building fast lightweight apps, but the UI portion is missing many controls and documentation from Telerik, if the controls do integrate.  

ComponentOne seems to have a good handle on it, but we prefer Telerik if we can use it.
