Poweramp Equalizer frequency selection

[Blackfire74]

Hello, this request is related to PA EQ app not built in EQ from Poweramp, but I guess it might be implemented in both.

I think that would be nice to decide how many sliders in graphic eq you want by number (just like in parametric mode), and choose frequencies by hand , too. For example: 4 sliders, 50, 105, 400, 4200 Hz. Or just one or two with frequencies I want. Of course Q parameter should be automatically set like it is in graphics mode.  How about adding HPF and LPF  to graphic mode? Just two rotary knobs for frequency range change.

Th8s way we will have full EQ setup in one screen: frequencies sliders (pre-programmed as is or chosen by user), tone knobs for treble and bass (you can add mids too) and high and low pass filters.
