Will you add type able box to specify frequency in the built-in equalizer?

Hello.
I appreciate the works for adding built-in equalizer that works in music and video.
There's one thing that's bothering me. That's the slider for the frequency. Picking exact frequency after 1 kilohertz is hard. Therefore I ask for type able box to specify the frequency.
I already put in an issue for feature request here #810
Will you add that feature in flow?
