Can be as post build process step or button saying "Minify all ref. assemblies".

Add support for DataVisualization assembly or prompt message that we don't support it right now.

Optimize binary and text resources like fonts, images...etc. Especially for the RichTextBox.

Convert the interfaces and base classes (i.e. non UI specific logic) to a portable library.
We intend our solution to share Models and View Models between WPF and Silverlight (and more in the future). Our intention is to use Portable Libraries to achieve this. The biggest issue we have is down to the Telerik assemblies. Classes and interfaces that are shared between WPF and Silverlight could/should be in a PCL assembly.

it would be cool if your controls can be used in Xamarin

Counting distinct items is often necessary in a grid.  Showing the number of customers in a list of orders for example (one customer may have multiple orders listed in the Grid).

Would be nice to have guidance on how to integrate Silverlight controls with LightSwitch Project Types.
