Speaking of speed, using jQuery.each to iterate over an array is bloody slow.

Did one of these to test:

(also a lot of stuff to confirm my thoughts on where var’d stuff went)

That also brought me to trying iterating over a jQuery collection in array style:

I wonder how big an impact any of this speed stuff is going to make, though.
