I would like to suggest the following improvements related to localization's:
- Option to specify which culture to export.
- Prompt the user with a detail message before deleting a language.
- Ability to choose which cultures are active and which are not, if a culture is not active then not to be display in the culture picker in front-end but to have the ability in administration to add content for any language even if is not active.
- Add culture picker for Content Items
