I bet someone can handle to to what my gonna to propose
the plugin, when you install it, t creates "languages" link in the adminpage "appearance" sidebar.
the page there generated dynamically, getting info on some site(doesnt matter for now where it'll be stored), showing available languages for the corresponding vanilla version
lets say a < ul > list with the flags, language name, short info and download link
when you click "download", it downloads the language in plugin's folder, back's up current localization file, and makes this localization active
i think it would be really easy way to manage languages for end-users
in the future releases updates and version checks can be implemented
guys, can anyone try to do that kind of plugin? @oliverraduner
