Click and drag to transpose values

Click and transpose/drag/shift... I don't know what the correct term is, but the video clip illustrates it working in Logic.

It could speed up editing on the Scalings page maybe, especially combined with the ability to edit values of several messages simultaneously.

I see, you are suggesting that the control is edited via mouse instead of entering a numerical value?
That would work for MIDI values [0 127] only though, floating point numbers can't be edited this way.
