My Sensorpanel is design to fit in the old Gadget area of the desktop, and to reduce the footprint I implement a minimalistic approach which does not place values on the SensorPanel. If a color other than green shows, I need to investigate.
Food for thought: add a selection in the Bar Display Tab that allows specifying whether the Sensor Name and/or Sensor Value display in a Talk Bubble on mouseover of a Bar displayed on the SensorPanel.
Edit: minimized further... removed all values
