Logging on behalf of a new Koha customer: When looking at a biblio record which has a linked heading (author, editor, translator), Koha will present other books with the same heading (i.e. all the books edited by the same person); however, if there are no other books with the heading, it does not look like it responds at all: click on it, and it reverts back to the record from which the user is clicking on. This is correct behaviour as per every other search in Koha, but as it looks to the end user like the search hasn't done anything, the customer thinks this is a poor user experience and would like it to be clearer that there is only the one result found.
