Hide FFT widgets?

[encoded-evolution]

Hi @ChrisVeigl - I like using FFT as filters, using power as output. They are straightforward to set up and for some purposes are great as they don't suffer from "ringing" as butterworth filters can. But, when used this way, I don't need to see the graphic output.

Is it possible to add that checkbox that hides the widget in an upcoming release?

ok, marked as planned improvement
