Magnolia Messages is a custom Magnolia module which adds a GUI for translating messages inside the magnolia admin interface.

This is how the translation page looks:

The module needs to be installed as usual, declaring an additional dependency into your pom or copying the JAR file into Magnolia webapp WEB-INF/lib directory.

You also need to configure in magnolia.properties:
