Use the version of this workflow that matches your version of Essentials. 

In 3.8 the Buffering step will not be able to remember your buffer selections when previewing the buffer, but everything else should work fine.

3.9 was the original version of this workflow.

3.10 has been optimized for speed (as much as is possible) and cleaned up, also the HighlightBorderColor and HighlightFillColor are now exposed as global variables in the Workflow if you wish to change them. This is stil possible in previous versions, but you need to find the client commands that set these in the initialization steps and change them manually.
