The ‘footprint value’ in the PCBnew is meaningless for me, so I always want to hide it in the PCBnew, but after I switch off the ‘footprint value’ display by manual, when I switch to another pre-setting display, the ‘footprint value’ will appear again?
You can also use Edit → Text and Graphics Properties, choose Values and untick Visible. Then they all will be hidden and you can control them with Hidden Text in the Objects tab.
