Yes, I think the smart method would mean that AIDA64 would only automatically update the label when the label is shown on your layout. To break it down, when you initiate a source change:
1) For Simple Sensor Items and Sensor Items: when you have the Show label option ticked, AIDA64 will not update the label automatically. When that option is unchecked, AIDA64 will update the label automatically.
2) For other items (Graphs and Gauges) AIDA64 will update the label automatically.
Does it sound like a good practice to you guys?
