Wait up, this is getting confusing

My first answer was because I thought they wanted the Calibre index # sorted
{id} is the CALIBRE index number seen at the end of a folder name
Code:
C:\Users\thedu\Calibre Library\John Schember\Quick Start Guide (1)
{identifiers:isbn} finds (catalog) Ids like ISBN
Kovid, can this label in details be changed to
Identifiers, thus making it real clear which we are talking about ?
