Working on user timeouts - now have the user timeout time being nicely tracked in the back office with a bit of injector magic both on the client side and the server side with filters. Now to wire up the call to get remaining seconds if a request hasn't been made for a specified amount of time, then we can add UI notification about timeout period.
