I have owned several Line 6 guitar processors including the PODxt, PODxt Pro, POD X3 and my latest, the Spider Valve MkII 212.  Of all the features on the various units, one of my favorites is the reference dots on the PODxt.  When you make a tone, volume or gain tweak by turning the appropriate knob, the display shows a reference dot to indicate the value of the setting before the knob was turned.  This feature was omitted on the POD X3 due to programming reasons per Line 6.  This feature is also not available on the Spider Valve, so when I turn a knob to make a slight adjustment such as a minor volume increase or tone tweak, I can't tell where the original setting was because the value jumps to wherever the knob happens to be at the time of the adjustment.  This makes minor tweaks on the fly very difficult.  Of course that's not a problem when I'm using Spider Valve Edit with the amp connected to the computer via USB because I can see all of the settings.  Is there a way to get the amp to display the settings before turning a knob to get a reference point for the values of gain, tone and channel volume?  Or does anyone know if there are plans to add the reference dots back into the display with a firmware update?  Thanks in advance for info or tips.
