The Phosphorum live edit syntax highlighting is terrible

I've posted this before but I think that it needs repeating. The Phosphorum javascript loop for the syntax highlting in the editor is so terrible that it freezes the sad lonely single Firefox thread to the point that it can hardly animate the twirling icon on post and it makes scrolling ultra slow. People before have proposed editing in a separate editor and pasting in. I'd personally like to be able to disable the editor and to only use the Preview.

From my perspective all that I get for this CPU breaking deep loop is a light grey hint on certain sections. I'd like to be able to just kill this feature.

I agree, it is horrible and I'd go so far as to say it is useless and extremely buggy, not having it would be better, just having the preview is good enough.
