Right now, Figma automatically stacks new layers in Auto Layout with the “Last on top” in the Canvas stacking. While you can manually change this for each frame, there’s no global setting to make "First on Top" the default.
Having to adjust this every single time slows down the design process. It would be much more efficient if Figma allowed users to set a global preference for stacking order—just like how we can customize nudge values.
Honestly, "First on Top" feels like it should be the default, with an option to switch if needed. This small change would save a lot of time and make Auto Layout much smoother to work with.
