Timeout counter

I suggest adding a timeout counter to the D-Tools Main page where it can flash red a minute or so before timeout. As the number of D-Tools users has grown in our company, we were forced to shorten the time out time that D-Tools can stay live while idle. Since a few of us engineers work in Visio and CAD through D-Tools we constantly have to close down our projects and close D-Tools just to have to reopen everything when the clock times out. a visible time out counter with a flashing alert would be very helpful for keeping us online in D-Tools.
