[otrs] Sorting queues: ticket with last customer reply to the top

[Marcus Sobchak <lists at localguru.de>]

Hi,

since a few hours I'm trying to sort the queue view in that way, that
the ticket with the last customer answer is always on the top, like in
an email inbox. I played around with the settings in
"Frontend::Agent::Ticket::ViewQueue" but can't figure it out.

Ciao!
