When I accidentally click on an input that has more than one item, "apply to each" is automatically created. However, it does not allow undo. I cannot drag the step outside of the loop even after I manually correct the input that results in the loop. I had to start over and recreate a large step such as a SQL insert step that can have over 20 input values.
We should allow the step to be dragged out so the auto-created "Apply to each" can be deleted afterward.
Broadly speaking, after a step is created, there is no undo. Having an undo can definitely improve our productivity of creating a flow.
