1) We should add a restriction to length so if someone posts a long piece of code, then we all are not scrolling to the bottom, etc.

Hmm not quite sure what you mean.
Skaperen has post a long code here looks okay to me.

2) There is no select all in code box

Looks okay.

3) (more major) and of course the original problem of copy and paste to advanced editor causes every word to be in code tags....but not the quick editor.

A little annoying some time,this batter me very little so it's okay.
