CW captures and indexes a wealth of metadata from documents & email which, although exportable, can't be seen by reviewers through UI.  For instance, I have reviewers that would like to see Author metadata for loose files, but there is no way to add this field to the metadata display.  In V70 the displayed metadata fields are something like this:

Loose Files: Doc ID, Custodian, Last Modified, Filename

Email: Doc ID, Custodian, Language, Last Modified, From, To, Sent, Subject, AttachCount, Attachments

It would be great for users (or even administrators) to have the ability to add/remove fields from the displayed metadata so that doc reviewers can have the most relevant information readily available.
