The latest plugins from Fractal Audio include a very handy feature.
When selecting two cabinets or IRs, to adjust their blend, you don’t need to manually set the levels for each one, which changes the overall volume. You simply turn the “Blend” knob, which controls the ratio of the signal levels between the first and second, while the overall volume remains constant and is adjusted separately.
It would be incredibly nice and convenient to see something like this in Quad Cortex.
