For internationalization, it could be very helpful to support RTL (right to left) languages like Arabic or Hebrew.
I understand that we could rely on localization efforts of the communities in regions where these languages are spoken/written. However, I reckon in this case we could receive at least three different solutions and will not get ahead with translations until these solutions are ready: https://translate.shopware.com/project/shopware6/discussions/30. Hence, IMO it would be better to have a solution by ourselves ready to be used by the community.
In language (not country!) settings, it should be possible to define whether a language is RTL or not. Depending on this admin option, we could deliver a slightly adapted CSS that overrides the standard in the storefront view.
