This is all great news!

However, a key feature of the Mapper, the functoids, is a great abstraction when you want it, but is obfuscation when you don't want it.

Ideas:

When you hover over a functoid, show the properties.

Simplify getting to the properties, rather than having to go to the Visual Studio properties window.

Allow grouping composition and copy/paste of a group of functoids.

Comments, like the Orchestration Designer Group shape, would be great.

Much clearer handling of loops and repeating constructs would be helpful, perhaps like the reply about two-level (complexType and simpleType) mapping would help.

thanks
