Venutius

This plugin is designed to simplify, improve and make the management of BuddyPress Template Overloads more accessible.
Overloading in BuddyPress is the process of customizing the membership pages by replacing default files with your own content.
It’s a process that can become burdensome to manage since unless you are very organized it’s easy to forget which files were changed and the changes made.
Let’s say you inherited a BuddyPress site, or did some customization a while back and now want to know exactly what you did?
This plugin can help you, it will scan your site, show you which templates have been overloaded and allow you to easily compare those overloads with the default files.
Both traditional Theme Dependent (files stored in Child-theme) and Theme Independent Overloads are supported.
Includes support for the forthcoming BP-Nouveau theme.
On loading, BP Template Overloader will scan your theme directory and find any existing template overloads that are in place.
Any that are found will be highlighted in the Template Overloader tools page and you will have the option to compare the current 
overload with the current default file, so you can understand if you need to bring your overload up to date.
You will also get the option to migrate any Theme Dependent Overloads (TDO) to Theme Independent Overloads (TIO).
For files where no overload is in place, you will have the option to view the current default file and to establish either a TIO or TDO for that file.
