Starting pdfToolbox 12.2, Process Plans allow multiple selections of steps with shift+click in order to re-arrange steps in a process plan. Move all the selected items together wich click+drag.

Prior to pdfToolbox 12.2, the canvas could be moved by click + drag inside the canvas. Since click + drag is now used for multiple selection of steps, the gesture for moving the canvas has been changed to SPACE + Click + Drag.

pdfToolbox 12.2 onwards, you can select Process Plan items and move them out of the canvas to allow auto-scrolling.

Since pdfToolbox 15, you can select Process Plan steps and align them horizontally or vertically.
