This simple addon adds a new block called "Breadcrumbs" which works similar to Auto-Nav block with specific parameters:
Sub Pages To Display -> Display breadcrumbs trail.
Custom template -> Breadcrumb
So this Breadcrumbs block intended to help new concrete5 users to add breadcrumbs to their website in easier way.
Also, it prints the current page inside <strong> tag (that should be good for SEO) and links to the homepage as the website name in anchor text (and not standard 'Home'), which should also be better for search engine optimization purposes.
