A feature similar to Adobe Audition that allows something of a rubber stamp painting with target crosshair for precise alignment to visually correct and match frequency specific replacement, that accounts for log scaling (or current scaling). And with the same painting thing with dodge/burn like how Photoshop affects intensity of underlying frequencies, and (NEW) include intensity weighting of what is affected by the dodge/burn (affect the low dB more and the higher dB less, or vise versa).
The current method of marqueeing a rectangle with dials is useful to a point, especially when addressing zones to be affected, but it useless at the granular level, which the painting method would make all the difference.
