Steps are the individual building blocks of a workflow. Each step can either be a Filter step or an Action step. When the workflow trigger fires, each step is executed in the order they are saved.
At all time, the buttons Add filter step and Add action step are visible at the bottom of the step list.
Steps can be reordered using the arrow buttons in the the top right corder of each step.
Remove, minimize and restore
You can also hide/minimize and restore/maximize a step. To remove a step, use the X button.
