Panels Breadcrumbs allows you to set your breadcrumbs directly from Panels configuration, and also allows you to take advantage from Panels arguments and contexts as placeholder tokens.
The Breadcrumb configuration is saved along with the page, which means that if you export the page through a Feature, the breadcrumbs you've set will also have been exported.
New in 2.x
Support for Panelizer and configurable breadcrumb panes. Panelizer support requires a panelizer 7.x-3.x version from at least 30 November 2012.
