I was talking to the guys from Flex this weekend at the ARRL Centennial convention the subject was brought up about future ability to be able to right click RX filters per mode and customize and save them. PowerSDR had this feature. For example, edit the 1.6K button, rename it to 2.0K and change the low cut and high cut to 300/2300 Hz.
I'd like to see how much interest there is in this ability. I know I would like to have different filter buttons than the default six buttons.
