Show cms layout "source"
When I assign a layout to a category/product, all settings from the “global” layout are initially applied. However, this only applies until I make changes within the category/product via the “Layout” tab—which therefore only apply to this entity.
This often leads to confusion if changes are made to the “global” layout at a later date and these no longer affect the specific category or product. If the above scenario occurs, I still have to make the changes at the category/product level for them to be visible.
At this point, we need a note in the “Layout” tab that indicates that changes have already been made at the category/product level and that any changes to settings (filters, etc.) at the global layout level will no longer automatically apply to these.
