Just a quick suggestion:
Often when I open or create a big transform the default is for the steps to be arranged from left to right orientation across the screen. This is not the most efficient use of screen space. I often have to manually rearrange a big transform vertically in top-to-bottom orientation in order to be able to see the steps and the right-side window pane clearly.
It would be nice instead to have an option to either transpose a right-left orientation to top-bottom (stacked vertically) or similarly to set top-bottom as the default orientation when
adding new steps to a transform.
