NNot sure right place to suggest, but I really think u should at least add an option or somthing of the like to make code blocks simple 200 - 300 px boxes with overflow.
I've tried to stylize this on post, but it never alows me to submit.
Some code post are extremely long (like my own) thus it would make since to make them scrollable boxes, or at least allow the option.
Thanx,
JD
