The Grid element allows to place cells in grid in the user interface. Whatever one does there applies to the current breakpoint.
In the other breakpoint, the manipulated cell will retain its autoplacement. Then, you can go to a different breakpoint and adjust the placement of the cell there, and of course it can be different than the 1st breakpoint you have worked on. Then, when I realize I don’t like it for this breakpoint, and rather return to the autoplacement, I can right-click on the cell, and the context menu will offer exactly that option: “Use Auto Placement”.
Problem: this will apply to ALL breakpoints, I will loose the carefully constructed placement on all other breakpoints! This may be intended behavior, but I find it very non-intuitive, and it actually looks more like a bug to me.
Feature request:
Option 1: Apply the “Auto Placement” only to the current breakpoint.
Option 2: Offer 2 context menu entries [Use Auto Placement (this breakpoint)] and [Use Autoplacement (All breakpoints)]
Option 3: Single menu entry, but have a pop-up that lets the user chose between those 2 effects.
I personally would prefer Option 2.
