Two ways to draw
- Drag → pull out a measurement box that measures width and height (the W badge is centered on the top edge, the H badge centered on the left edge)
- Click the head, then the tail → draw an I-beam measurement line that measures the distance between two points (Shift on the second point locks it orthogonal)
Edge snapping & alignment
- A crosshair reference follows the cursor as it moves, auto-snapping to content edges
- Magnifier alignment: the drop point is the real pixel you see; hold

The dimension label is editable
- Double-click the dimension label to change it to any number; for a W×H annotation, editing one side auto-scales the other proportionally
- Multiple units are available, so you can hand the collaborator the size you intend; setting the unit to "None" = a pure I-beam line, used as an annotation
- "Reset to measured" reverts it to the real size
