Hi,
In order to save space for other buttons is it possible to change the behaviour of the pause button:
During a crossfade when you press pause the go button and pause button do the same thing : go forward. So, at this moment, they are the same.
It could fine that as soon as pause is pressed, it becomes a "go back" button. So you would only need two buttons to handle the stack.
... And the "go back" function would remain available by pressing the top right corner of the screen.
What do you think ?
