One thing that always bothered me about complex desktop applications like Adobe Photoshop or Eclipse, or even Desktop Linux is finding out how to use the more advanced features (or, truthfully, some of the basic features). I’ve always liked community response, so I’ve been on a number of mailing lists and it’s usually really helpful. What if these types of useful feedback were available within the application itself? You could literally just type a question into your help box, and a minute later you would get answers.
