Orchard Buckets allows you to create "buckets".
A bucket is configured to hold content items of a specific content type.
An example of a bucket is a Blog: a blog is a list of BlogPosts.
Similarly, News could be a bucket of NewsItems.
Buckets are hierarchical: they can have a parent bucket, and each bucket can have children.
Buckets can be pinned on the admin menu, similar to the way the Blogs module renders its menu items.
The module comes with a couple of recipes to quickly setup commonly used buckets, such as Blogs and News.
