In Version 9, there are two types of Breadcrumbs:
If you see ellipsis dots on a tab, it means that the browser window isn't wide enough to show all of the tabs. Click on the ellipsis dots to see what additional tabs are available.
Everything in the admin interface can be considered a "record". A product is a record. A customer account is a record, etc. There are many types of records in the admin interface, and most of them can be edited. For example, you can edit a product and change the retail price of that product.
There are two types of editing in the admin interface: "quick edit" and "full edit". Some types of records only have quick edit. Some types of records have both quick edit and full edit mode.
In Version 9.0005 and later you can reorganize tabs.
