# Graph Editing

## Scene Links

- Create a link by dragging from the source node handle to the target node handle.
- A regular click or double-click on a link must not change the graph.
- Delete a link only through its context menu: right-click the line and choose **Delete**.
- Delete a node through the node context menu: right-click the node and choose **Delete**. Removing a node does not delete the scene from the scene list.

## Main story start

- Right-click a node → **Start scene** to mark the main storyline entry (purple **START** badge).
- Only one main start per project. **Run** in the editor header uses this node.

## Side storylines

- Side storylines are isolated subgraphs: no links to the main story or to other side storylines.
- Right-click a node in a free component → **Side storyline start scene** (blue **SIDE** badge).
- The menu item is hidden if the connected component already has a main **START** or another **SIDE** marker.
- Side storyline links and selected cards use blue (`#0078d4`).
- **Start from this scene** is not available on side-story nodes.
- Scene properties show **Side storyline title** when the scene has a side-start card.
- During play, side storylines appear as tiles on the control panel (under Music). Clicking a tile jumps to its first scene and remembers the main-story return point.
