As a process designer, I want to be able to drag a new field immediately into its correct position, to avoid need to fix its position right after
Currently, dragging a new field into form builder drop area adds the new field as the last field of the form.
Desired behavior is to be able to drag and drop a new field into its own place without need to fix its position right after.
This might be good issue to start this iteration with, because this should allow to review the current state of the form builder implementation and to do the necessary refactoring while allowing also this to be implemented.
