Language, currency channel connection

[riczi-ricz]

1. As a store owner, I want the ability to configure a country and language selector for my store front that only displays the countries and languages my business supports. The picker should show country names in their primary local language and only display supported country-language combinations (see pic below), as configured in the Saleor dashboard.

2. As a store owner, I want to configure which countries are associated with specific sales channels in the Saleor dashboard.

3. As a store owner, I want to define the default language for each supported country in the Saleor dashboard, with predefined defaults available (e.g., German as the default for Switzerland).

4. As a store owner I want to have multi localized store optimized for SEO.

• localized urls in sitemap,
• links alternate in HTML meta should contain only combinations defined by store owner.
• short urls, locale pl_PL should be shown like /pl/, fr_CH should be shown like /ch/fr/.

5. As a store owner, I want to set a default store locale that will be accessible via the root path (/), without the country and language prefix. For example, if the USA is the default locale (en_US), a URL like /us/en/ should redirect to /.

6. As a store owner I want to be able to select default store locale which will be available on the / path without country and language prefix. Ex. if USA will be default locale url /us/en/ should be redirected to /.

7. As a first-time store user, when visiting the root path (/), I want to be automatically redirected to the version of the store that matches my browser's locale.

8. As a store user if I change my locale from proposed one I don’t want to set it again.
