> [!important] goals
>  - have all the notes about a subject
>      - using [[obsidian plugin breadcrumbs|breadcrumbs]] hierarchy with `up::`
>      - auto-updating
>      - see what the note talks about
>          - `title` and `description` attributes

> [!note] implementation
>  - inside a custom [[obsidian callouts|callout]]
>      - make text smaller if needed
>          - `query` or `smallquery`
>      - wrappable callout (spoiler)
>  - [[Depth-first search]] order

# The query

> [!query] Sous-notes de `=this.file.link`
> ```dataview
