Adjust the arrow's shape, style, and effects. The preview is on the right; use the buttons below to export.
Drag the round handles on the preview. On the selected point, purple and blue Bézier handles control in/out tangents like in vector apps. Double-click the path to add a point.
Only the open arrowhead style is used.
The rings at the line ends on the preview move those endpoints freely; the lever sets arrowhead tilt where a head is shown.
