FlowLines Pro
The free tier draws unlimited straight and elbow arrows with labels, so it covers a complete flow diagram. Pro is for curved arrows, arrows that keep up on their own, and drawing flows straight from your prototype.

How the gate works
The Curved line style, Route elbows around other frames, Reroute arrows when layers move, Draw arrows from prototype links and Style presets carry a Pro pill. Choosing one without a license opens the Get Pro tab and the control goes back to its free setting. The plugin's main thread checks again before it draws a curved or frame-avoiding arrow, starts live reroute, reads prototype links, or saves or deletes a preset.
Arrows you already drew stay as they are if a license is removed. Reroute all keeps redrawing them in their stored style, curved ones included.
