Perhaps in the future we will look into that however at the moment we have our hands full with upgrading the .NET Languages Add-on, making SyntaxEditor for WPF, then after that upgrading SyntaxEditor for WinForms to use a lot of our new designs.
You are right, that's the reason I hope someone else would do it ;-)
Because currently I do it myself, and it works most of the time.
So the need is not urgent. It's like the intellisense for c#. I implemented it although myself and it worked for 95% of the cases. But it needed some time.
