Where are tickets solved? (3.4.5)

hello all,
i’m using rt 3.4.5 since few days, and it is a great product.
But i don’t understand something:

  • why can’t i display solved tickets on the firt page?
  • how can i display tickets managed by other people?
    When a user took an opened ticket, it disappears from the list on my own
    page. But it is interesting to know what people took it.

thanks in advance,

gerard
