currently, if you leftclick&drag the editbox of the “Mul” value in Advanced Edit, it adds/subtracts 1.00 to the current value; rightclick&drag adds/subtracts 16.0.
also, the value can be dragged up to negative values, which really does not make sense.
what i propose:
leftclick&drag unit: 0.1
rightclick&drag unit: 1.0
lower bound: 0.0
