The Content Report module provides "simple" report dashboards about the content stored in the repository and some tools to manage that content more efficiently.
I began working on translations for French labels, but as you can see in the following screenshot, the JS Library being used (jQuery DataTables) is not currently internationalized. We should look for a way to translate its labels.
The module has dependencies toward bootstrap3-core and bootstrap3-components.
As the module itself already has/embed bootstrap resources (JS and CSS) and as it seems the boostrap module is not being used we may consider removing these dependencies.
In the overview view, 3 metrics are being displayed (see screenshot below) :
Pages
Templates
Registered Users
From what I understood reading the code (I may be wrong) the Templates metrics seems to be the number of installed modules on this Jahia site. If it is right, we should rename this metric to something like "Installed modules", templates is used for others things in Jahia.
