[Koha] staff member responsible of loan/renewal recorded in issues?

[Giuseppe Angilella]

Dear Kohaers,

is the information concerning which staff member was responsible of a loan 
or renewal of a given item recorded anywhere in the database? I couldn't 
find it in the "issues" tables.

Assuming it is not, it could be a relevant information to record, in cases 
where several staff members (or even all patrons) have issueing 
privileges.

Many thanks,

Giuseppe.
