Or can I add my tickets so i have a choice in each dashlet between my locked, my tickets, tickets in my queue and all tickets ?
(if this is not possible, can I create a new dashlet ?)

Can I change that so I can see all tickets assigned to me even if they are no longer locked ?

How can I set a filter that shows tickets only assigned to me ?
I understand state etc, but how do you enter the current username as each user would have a different selection.
