Hi @peter 
just a couple of things I wanted to flag from the Stage Traxx 4 beta:
Right now, there’s no option to disable waveform seek and progress bar.
 
During testing if I tap the waveform by accident, 
it jumps to another part of the song, 
which can be a bit of a headache. 
It’d be really helpful to have an option to turn that off.
Also previously in ST3 this toggled song list view if tapped which is a missing feature
Should be part of the “Safety” section in “Playback Settings”
