It would be great to be able to see which parameter you are adjusting when you turn a knob on your control surface. unless you have a mackie control or a novation sl (I use faderfox), it's easy to confuse mappings. It could be in the bottom left corner, where parameter values are displayed when you roll the mouse over them.
Just needs to show the parameter altered and the value as it changes.
Would be SO useful.
