Block Manager - an interface for managing Blocks in a Layout. Besides providing basic Block actions, it also provides Shared Zone linking, Block Parameter translation, changing the Layout Type, etc.
Layout Manager - an interface for managing Layouts, Shared Layouts, Layout mappings and User Roles and Policies. It also provides cache clearing for Layouts and Blocks and exporting Layouts to JSON format.
Roles and Policies Manager - an interface for configuring user roles and policies.
Content Browser - a standalone interface for browsing content from a backend system and selecting one or more items. It is decoupled from Layouts and has its own documentation.
