When the Remote Utilities viewer is viewing a host with multiple monitors, switching between the monitors is very clunky when done via the icon on the hovering menu-bar.
It would be great if one could open each monitor in a tab of the viewer, similar to what occurs if one guest connects to multiple different hosts.
It would be even greater still if it were possible to tear those tabs away into separate windows - then if the guest has multiple monitors also, one host-monitor can be placed on each guest-monitor by moving it's distinct window to the desired monitor.
We already have this feature in our wishlist among a few other features related to the multiple monitor use, so we will implement it in our future updates. Unfortunately, we cannot provide any ETA on the feature yet, sorry for the inconvenience.
