When working on some projects and articles in Expression Blend 3, Timmy Kokke noticed a few differences with Blend 2. Now he posts 9 improvements and new features that he really likes and enjoys.
One feature I would like to mention is intellisense. When working on smaller projects, you do not have to leave Blend to edit some code. It can be done right in Blend now, which becomes very handy when dealing with events for example. Intellisense even works when editing Xaml files.
