## Configuration

This plugin accepts the following configuration options:

**YAML options** (in `quartz.config.yaml`):

- `title`: The title of the explorer. Defaults to `Explorer`.
- `folderClickBehavior`: The behavior when a folder is clicked. Can be `"link"` to navigate or `"collapse"` to toggle. Defaults to `link`.
- `folderDefaultState`: The default state of folders. Can be `"collapsed"` or `"open"`. Defaults to `collapsed`.
- `useSavedState`: Whether to use local storage to save the state of the explorer. Defaults to `true`.

**TS override options** (in `quartz.ts`, for callback functions that can't be expressed in YAML):

- `sortFn`: Custom sort function for ordering files and folders.
- `filterFn`: Custom filter function to exclude specific nodes.
- `mapFn`: Custom map function to transform node properties (e.g. display names).
- `order`: Array controlling the order of operations. Defaults to `["filter", "map", "sort"]`.
