Multifeed Google Shopping Feed

Makes setting up feeds very easy - there's a bit of syntax to learn if you want to get lots of detail in there (start with a single quote in the expression editor and it drops all the options down for you) but following a big site migration from a custom setup to Shopify I was able to get product feeds for Google Merchant Centre, Meta and Klaviyo up and running in literally minutes. Probably half an hour all told for five feeds.
