For quite a number of my book entries I hold files for the complete book (parent entry). Now, many of these books are edited volumes.

I note 2 small improvements:

• allow to use the context menu/right click onto the parent entry for generating a new entry that crossreferences the selected parent entry (considering design discussion at UI: maintable: right-click menu: reorder items #6099)
• and whilst the crossreferencing already well uses many of the fields from the parent entry, several relevant fields are not used (yet):
  • The file/link fields should be crossreferenced, too, as to link to the parent's files/links.
  • The user should be able to flag user defined fields as shown in the crossreferenced entries (I can think of, say, the Printed field for a collection entry, or a field that specify the physical location at which a book can be found)
• Add option to make content of certain fields inheritable from parent to child entry
• Improve UI of entry table to account for crossref parent and child entries (see screenshot in this comment)

Together with #5484, #6404, #7057, these improvements would very much ease the use of/work with crossreferenced entries.
