Notes
Notes are plain markdown (.md) files stored in a folder on disk — colour-coded by folder — and edited in a live-preview editor.
As you write, you can link things together:
[[wiki-links]]to any note, subject or task by title (with autocomplete),#tagsthat group related items,@mentionsto reference a task or subject inline.
Each note has a backlinks panel showing what points at it, and every link becomes an edge in the graph.
