I would like "best match" as an option as well as "featured products" for templates. Perhaps there is a technological reason this has not been implemented, but it would greatly help sellers of one-offs (such as myself) not to have to have to update applied templates when something that has been featured sells.
Currently it's great to promote products but a pain when they sell unless you have multiples. It would be nice if it could just dynamically select a new "best match" product to replace solds.
