[Idea] - Post area - max height

This would mostly concern what is referred to as "walls of text".

As of right now, should I enter a discussion where the OP is a massive wall, see "ongoing updates", having to scroll down to the comments section is long and boring.... I'm also lazy.

Wouldn't it be possible to set a max height to the original post section and should the contents be longer than said max-height, the area gets an overflow set on it's y-axis?
