Was that Codeporium? I believe Noah Richards and Chris Granger worked on something similar according this this comment: https://news.ycombinator.com/item?id=3848543 https://news.ycombinator.com/item?id=3848543 I actually saw the Codeporium .dlls kicking around inside the DebuggerCanvas package. Most of the Visual Studio interfaces lack a lot of formal MSDN documentation, which has forced me to do some novel research haha. Edit: Oh, you are Chris Granger haha. I'd also like to thank you for the Visual Studio 2010 editor tutorials, while I have the chance. Light Table looks fantastic, and I hope it inspires a change within other IDEs as well.
