Is it possible to change names of Extension Apps?

Hello @rogerpenna,

First you can find the translations in https://l10n.xwiki.org/.
For some of the applications you mentioned (couldn’t find Review and WorkFlow):

If the language of you wiki isn’t listed, the application names are not translated. In this case, the default value is the English one.

From there you have two choices.

  1. You can translate the applications you are interested in https://l10n.xwiki.org/. But, this will require the release of the new version of the translated application with the new translation values. Once the new version released, you’ll need to perform the upgrade.
  2. The other option is to directly update the translation files in your wiki (but the community won’t benefit from your work). To do so, go to http://mydomain/xwiki/bin/view/XWiki/TranslationDocumentClass and search for the translation file you want to update

The second option is a bit technical, feel free to ask for details.

Hope that helps.
