I like to change Filter to Barber Pole.
Every time I restart Traktor, it's set back to "Filter". Any way to make it remember and stay on Barber Pole, for example?
No. You could map a button on your keyboard to initialize any setting element to your preferences. After starting Traktor you just hit the key and all is like you would like it.
But i agree that it should be exactly the way you left it last time.
