Email Templates & Packing Slip - Template

in the older version of cs-cart... there was editor for newsletters... invoice and packing slip...

I using the last version 4.13.2.SP1, but editor doesn't appear on button Design.

I want to edit my template invoice.... to have a column in front of product with Category,

and also on Packing Slip, price for products

There is a way to install manual that editor... from old version of cs-cart?
