[otrs] Changing the otrs queue look

I have a bit of a problem. People here that are going to use otrs do not like the way the ticket queues are shown: when you are working with a ticket, the thread associated to it is shown just as a list of subjects (they would like it to be a bit less terse). And when you select the list of tickets in the queue, it takes too much real state on the screen because it is showing the contents of every ticket as opposite to just a brief overview. The search engine's results would be more of what they wanted to see here. Or, as one mentioned something more rt-like. Can I change that?
