This is a minor thing, and could probably easily adjusted.
When hitting the Save button on a Dataflow step in the Procedure, the left side of the Save button is on top of the right side of the Procedure Cancel button.
In case a double click is registered when hitting the Save button, you could accidentally exit the Procedure and lose all your changes in the Procedure.
Suggestion: Align the button sizes
Bonus idea: Add a Save function that doesn't make you exit the thole Procedure.
