I’m working on Shopify theme and found some Shopify limitations, like clone blog articles or pages across stores, import pre-set theme settings.
I create a free app to solve this limitations - Exim.
You can manage pages, blogs and theme settings.
Export, import, clone, provide pre-set data for you customers.
Thank you for feedback.
App allow to move pages, blogs and theme settings between 2 and more stores. (export from source, import to destination).
In such case you can deliver demo data for customers.
What do you mean by “everything”?
Products - export/import feature provided by Shopify
Navigation - there is no API for navigation menus.
What objects is most important for you? I will think about adding it in future update.
