All, As I was [one] of the submitters of the manual notch filter, I have given some thought on how it can be implemented. Open discussion. I like to click on a signal to do something with it, and I am dedicated to the mouse. However, that is not going to work, as clicking on a signal moves the frequency there. How about holding down <CTR> then clicking on the signal? A <CTR> double click removes it; another <CTR> click on another freq adds another notch. Shift click anywhere removes all notches. The depth/freq width is preset in the menu. Another important thing is to show the notch(s) on the display. Simple but effective. I am familiar with MixW notch, and it uses a drop down window. That is cumbersome and slow compared to a <CTR> click.
