I want to have two presentations stacked vertically, which present different aspects of the same object. I used `a stackedVerticallyArrangement`, but I want them to be a) different initial sizes and b) have a draggable splitter in between, but this doesn't seem possible. So my questions are:
1. Do I need to use two separate panes?
2. What is the use case for #stackedVerticallyArrangement? I.e. how does it differ from using two panes?
Thanks!
Cheers,
Sean
