So I managed to convince client that to separate retail and wholesale functionality, we utilise multisite (this did not just pertain to customer groups FYI, many little mods that the settings would not handle).
So far so good (awesome in fact!).
Question: I have several small page items eg. a message in footer explaining that all prices include tax. On the subdomain, I wish this to say the opposite. Should I simply use a function in my controller to check which store and output relevant text... or should I create a duplicate theme and make the required changes in that.
Further to this, my default theme uses several extensions, and I have noticed one alters the header.twig/product.twig - how does this work when using a new theme? eg. what happens to the modification structure??
