The FFT curve in Pro EQ is a barely visible blue line. A light shade of color within the boundary of the curve like Logic or Fab filter Q3 would make it much more easily visible. Right now using the 12th octave curve works as it is shaded but to pinpoint singular frequencies I end up using other graphical eq plugins.
And Solo banding is almost standardly needed in every graphical EQ plugin. It would be amazing if that and dynamic EQ are introduced to S1
