The Position field, found in the About panel of the Inspector, does not update live when dragging a part. This is true for both PCB and Schematic.

We have a principle that everything in Flux should update live. So the expectation is for this field to do the same.

This was pointed out to me today during a user research session. The user identified that knowing the position of the component during drag was important to them. And since we hide the toolbar during drag and that field isn't live, this isn't possible to know today.
