When responding to a post, I have to open a 2nd browser window. One to show the post Im responding to, the other to make my response. This is... fiddly.
Why not put the last post in a thread above the textarea we are given to respond in, so we can see what we are responding to as we respond to it, without having to have a 2nd browser window open?

Teach a man to fish, and he'll sit in a boat, drinking beer all day.
