Grey out calibration tab

I want to suggest to include the possibility the grey out the calibration parameters e.g. like shown in the picture:

"hintergrund": it now happened several times, that scrollable items were accidentally changed. While this might not be too harmful in the recognition or tracking tabs, it is risky in the calibration tab (as happened lately). e.g. the coordinate system can be changed by accidentally scrolling in that area, even if "fix" is checked. "fix" only inhibits the manuall relocation of the coordinate system in the picture.
