I figured it would be something along those lines. Thanks for taking the time to explain.
Flipping the axis like this would probably mean us having to rebuild the view. Then have some logic when creating/reading that data back to map it to the corrected axis. As arrays are 3D there are 3 possible flips, and 6 combinations ( 3 * 2 * 1 ) which makes the remapping logic more complicated ( as well as the associated UI ).
In your situation your just interested in "viewing it the other way" but modifying the data is actually easier to implement I think. Also it actually allows you to change the data instead of the view, which some people will want to do.
This will probably end up towards the bottom of the TODO list unfortunately, but I will add it to my notes to investigate.
