Please add the ability to fold blocks of code in questions and answers.
I have now had several questions (like this one) where I have posted code simply because I know if I don't the first comment's almost certainly going to ask to see it. Like the example, the code is actually ancillary to the question, but it dwarfs the actual content.
Why can we not specify somehow that a code block be folded. If not that, I personally would prefer all code blocks to be folded by default.
