That's waste of time since post caching/temp. should be really easy to implement.
Why would you want to copy everything into notepad, every single time if you don't really have to?
You don't want to, that's right, it's just a temp. solution. And as to that incident, I had just written two walls of text already, and I keep my mind better on the subject when I am watching related text rather than the white np++.
I'll also add that your method is annoying when you want to multi quote and re-read posts.
