A list of user groups for which the menu entry is visible.

## Installation

1. Add the jar file to {home}/appserver/lib
2. Create a messageEditorMessages\_<lang>.properties file for each language in {home}/appserver/lang, e.g. messageEditorMessages\_en.properties with the correct permissions.
3. To make all the messages editable, copy the contents of each customMessages\_<lang>.properties file to the corresponding messageEditorMessages file. Alternatively you can skip step 2. and rename the customMessages files to messageEditorMessages and just create one for the missing languages. This step is optional.

Note: Messages are often cached, you need to reload the page or press CTRL+SHIFT+R (Firefox, Chrome) or log out and in again to see the changes.
