I think I used Pathway with ParaTExt once. I didn’t get the results I wanted… (I use Pathway often with FLEx, so I do know my way around a bit). As a result, I rely on Print Draft for ParaTExt printing. It returns decent results, though recently footnote and cross reference callers aren’t showing up…
I have colleagues who use SILAS and Save to RTF, but I think moving them to Pathway would be a significant challenge (if I didn’t get the results I wanted, I wouldn’t know how to get them the results they’re after). Oh, and our entity does not have specialists to create custom CSS files.
