Hello Maxmp!
I'm Poweramp user for a long time and I love it!
I'm loving Poweramp Equalizer also. I'd like to sugest two features for Equalizer:
1) A possibility to set equalizer visualization as animated wallpaper.
2) My lyrics app can't identify musics playing in Tidal, could equalizer put a notification as a player, so my Lyric app could grab from it.
