I realize I’m responding to a two year old post, but it’s still valid. I don’tdon't understand people’speople's aversion to usability. (Looking over some of the Q&A on MSO, it seems like some people have an aversion to any kind of change.)
Code snippets don’tdon't have to be 1000+ lines to create a vertical scrollbar. Worse still are code snippets on one long line with a horizontal scrollbar. Those are a real pain to copy.
How can anything that makes things a little easier be a bad thing? Today, it should be fairly simple to implement in jQuery. SE already uses jQeury anyway. I think it’sit's worth looking into.
