There is no way to play backwards in Sequencer. I don’t know if this is a bug or new “workflow” thing, but it’s literally unusable if you can’t play time back. I don’t know how such basic thing could be not implemented early 
I think you guys aware of this, because play backwards button replaced with reset time, but if this gonna stay then it’s really a step backward 
I recommend to change Sequencer default hotkeys, what thoughts process was behind them?
- It is different to any other video editing tools
- It is different to Matinee
- Down to Play forward(?!?!?) and Up to RESET TIME, really?
