For the Development of Mendix applications would be very helpful to enable AppStore to deliver i18n packages that contain translations for core packages/Atlas UI. Currently English and Dutch is available and for all other languages translations have to be created.
Maybe this can be organized trough a better standard PO file, that way we can crowd-sourced translations via GitHub.

Every appstore module should have all relevant translations. I have special excel files import all those translations.
An addition after internal discussion: In case the app is using components from the app-store, it might be even helpful to also have a list of translations as part of the app-store-metadata.
