[16.11.1] Added new themes for invoices, quotes, orders, receipts etc

Adopted the new “themes” function instead of “view templates”, but I have a problem - instead of the title for Sales Invoices stating “Invoice”, I need to show it as “Tax Invoice”. How do I customise the template for sales invoice template specifically?

You can’t make theme specifically for invoices. Themes are always universal (this is on purpose). But that shouldn’t be an issue.

In theme, where {{ title }} variable is used, simply replace that with:

{{ title | replace: "Invoice", "Tax Invoice" }}

This will apply replace filter to title variable so if it contains Invoice, it will be replaced with Tax Invoice.
