Would be extremely useful to have the option to preview our prints in the actual color the piece is being printed in. I own a Davinci Duo - being able to verify that the prints and the support are in the colors I want them to be, especially when I'm running a print with several multipart prints with different processes would be extremely helpful. As it is, I must generate GCode and import that into XYZWare to verify proper setup, resulting in needlessly long iteration times.
Version 3.0 has implemented this feature. You can change the preview coloring to "active toolhead" so that you can see exactly what parts are printed with each extruder.
