Yes, I have finally taken the plunge. My stats show the adoption rate for Silverlight 4 has reached 78%, which is pretty close to my target. The immediate improvements you'll notice are right-click context menus for the textboxes... As well as support for mouse wheel scrolling. These are both small, simple, but much needed features. I'm still working on improving real-time highlighting. And I'm still on my quest to figure out word wrapping. Meanwhile, I also have some ideas on how I can further improve the benchmarking feature. Look for another release coming next week.
