BP Template Overloader is an attempt to make the overloading process much more accessible and easier to manage, it provides a simple yet powerful interface which displays all available overload files along with their status, where overload files are detected it provides a viewer that compares the overload with the current BP master file. Template Overloader also provides the ability to migrate to a Theme Independent Overload. It’s also built to help you migrate to the forthcoming BP-Nouveau theme should you want to.
