Units can be published. Once published, units are available for reuse.
Publishing can happen at the Unit level. When a unit is published, all components within it are published. If a component in a unit also exists independently of a unit, it will also be published.
Quick publish concept for reused components: If a component is published, it will auto-publish in any unit where it is referenced, unless there has been an override of that component in a unit, in which case authors will be prompted manually to accept the changes.
When a Unit has been published, it is available for reuse in a library. If some individual components in a unit are published but not all components, the unit is not available for reuse yet.
Units can be tagged
Units can be copied
Units can be pasted
Units can be added to, and removed from, collections
Collections can contain a mix of both components and units
Subsection and Section support
Subsections and sections can be imported into Libraries (see import requirements below)
Subsections and sections are read only, to start. They cannot be edited, nor created from scratch in libraries.
Each subsection/section in a Library has a tile representation with a title and description
Subsections/sections populate among the components and collections on the library home
Subsections/sections turn up in search results and can be sorted and filtered
There is a Subsection tab and a Section tab, which is a filter on each respective as a content type
Functional requirements: Course Side

Units can be copied from a course and pasted into a library
Full courses can be imported into a Library. Authors can decide at the time of import what level they want to disaggregate the content in the library - unit level or component level. (Later, section level )
Subsections and sections will be read-only, to start
On import, content get added as published components, but there is no sync to the original course, the content in the library does not reference the course, it becomes the defacto source of truth version
