This page is magical
It allows you to modify all the elements of your store, regardless of its language.
Example:
You have set your store in English, but you are not satisfied with the "add to cart" button text, and you prefer to replace it with "add to my lovely cart."
Nothing could be simpler:
Select the language of your store
Search for "add to cart"
Change the text
Save
That's all.
In this way, you can customize your entire store
