please take a quick look to see if the general approach looks good to you.

I definitely like the general direction of pulling out a view to specifically represent the answer here. I had in mind that we could go a bit further and have a generalized AnswerView with a similar structure that where setAnswer takes an IAnswerData (I think the widget would handle the hidden appearance in that setup). That would get us something that's simple to then use in the hierarchy later.
