Theme by Domain (How difficult would it be to implement)

I've seen Product by Domain and Theme by Domain addons but I would love to look into how complicated a "Theme by Domain" addon would be.

If the moving parts are not too numerous I would be interested in writing it myself and pushing it up as an open source addon.

Template by domain would be quite simple.

During init(), preset the store_template_catalog setting.
https://github.com/litecart/litecart/blob/dev/public_html/includes/library/lib_settings.inc.php

  self::set('store_template_catalog', 'othertemplate.catalog');
}```

Product by domain requires a new field under edit product and it's controller ent_product.inc.php for defining what domains should return the product. Then you would have to add the condition to pages/product.inc.php, pages/search_results.inc.php and includes/functions/func_catalog.inc.php.

Awesome, I'll try and make it happen. I don't actually need product by domain (since I already bought it)...I was just wondering if "theme by domain" would need to touch as many sections of code.
