The Manage Theme Resources functionality is integrated in all our themes since 29.07.2015.
It provides a powerful way to modify the resources added (overridded) by the specific theme.
Each our theme has a Manage Theme Resources menu item.
On Manage Theme Resources page you can see and modify all resources for the theme.
You have the option to change the language - this will automatically re-populate the grid with the resources for this language.
The "Include Admin Resources" checkbox will show the admin resources for this theme.
