I would be really nice if titles in the table of contents and references to classes were hyperlinks that took you to their definition. I find myself jumping around using find which is suboptimal.
Since there is a fair amount of inheritance going on, I often find myself having to walk up through the parent classes to find the description of properties and methods. It would be awesome if a child class had a condensed list of properties and methods that it inherits. If these were hyperlinks to the parent's definition, that would be ideal.
Another nice-to-have would be more inline images of various controls. Sometimes it's hard for me to visualize a particular control from the description and a picture of it would really help convey the purpose of each I think.
Overall I think the documentation is sound and I definitely appreciate the effort that has gone into it, keep up the good work.
