- use predefined template files
- processes/nodes: drag and resize, use image, clipart gallery, edit/hide process label, hide nodes
- arrows: draw arrow by directly connecting processes, add one or more flows to arrow, enter quantity, choose color, editable arrow label with flow name and quantity, add arrow bending points, stacked arrows, change stacking order, numerous arrow options (rounded, orthogonal bends, arrow head, arrow tail, perimeter line)
- units: manage various unit types each with own color palet, show percentage
- scaling of flows (to max flow or absolute value) per unit type using slider
- print and export diagrams (jpg, bmp, png, gif, emf)
