On the 1. I think that the custom field on the Ticket Details form is not working, because the work time must be entered in every post in the ticket and to be calculated when the ticket is closed.On the 2. Adding the ticket in the past time is important for small startup's like our company. We are in the IT branch and our engineers resolve tickets most of the time before some one can enter the ticket in the system. And after a hard day work we enter the tickets in excel. We tested other open source ticket systems and the option for adding ticket in the past was possible, but the system's war very hard to support. You ticket system is the first we liked very much and it was easy to support and update.
