Why an au window can’t be resized?

… because using scroll bars is annoying.

I’m using TineBoosters Equalizer v4 to eq my headphones. I can use up to 16 filters which sometimes are very close.
Characters are small if want to keep the whole screen in the window.
If I enlarge the eq screen I must use sliders.

A 20 30 % larger window would be ok.
A sizeable window would be good, having it fullscreen would be great.

Thank you for your attention.
