I would like to see all the load balancing options that we see in standalone mode ported over to the controller.

More standalone switching options are ported over to the controller also.  

Be able to add more DNS servers to the router.  If we could do 4-5 instead of 2.  

The controller Bandwidth dashboard widget could have an upload meter.  If we could have multiple WAN widgets on the dashboard.  For each WAN port.  Also separate ones for Download and Upload.
