Back vs. Tray

I open the drawer 92 times a day by accident trying to go back by swiping my thumb from the left because in 95% of apps on my phone, that is the behaviour.

If it has to be one or the other, I’d take Back every time. Or it could be a setting. Or, ideally, context aware — if I’m on my Day view or whatever, sure, drawer. If I move into a task or note or whatever, swiping should take me back, shouldn’t it? I can’t be the only person struggling with this.
