Thanks,
I've decided to ditch DoozyUI, I find it really restricted and not transparent. The thing that really did my head in was only being able to set one enter/exit animation for the views, and not have different directions (up,down,left, right) depending if different buttons were pressed.
I'm going to persevere with the standard Unity UI, DoTween, and Playmaker and see where that gets me. I figured that when I encounter problems, at least the solutions will be applicable to Unity/Playmaker, rather than the additional framework of DoozyUI.
