Extending the application
Just to clear a few things up. The SDK with Plug-in development is all C# based. Theoretically you will be able to use any language that the .NET Framework and that is CLS compliant to write plug-ins as long as you follow the spec.
I guess I was looking for examples and feedback from developers on which things they would like to control from scripts. I want this thing to really be flexible. So you can do anything you want with the system pretty much.
Feedback is really appreciated. Thanks everyone! Keep it up.
