Hue Tab

Can't figure out how to get it to work

I have HueTab installed, but it doesn't seem to do anything - it doesn't look exactly like your demo video and clicking the "H" button in the top bar doesn't show me options to enable colors, just access settings and things. Did this stop working? Was really looking for a way to add colors - not sure if it does it like this but was hoping I could assign color values to each note (A=red, B=orange, etc) so that as I use tabs with fret numbers, i can also start to learn the associated notes I am playing at the same time.
