The Journey plugin is designed to help users navigate and connect their notes in Obsidian by automatically generating a cohesive outline from their existing content. It enables easy exploration through forward-links, back-links, and tags, allowing users to trace the connections between their notes. The plugin offers several customizable features, such as the ability to exclude certain folders, avoid 'hub' notes with too many links, and create automatic links or transclusions. Users can also opt for high-contrast accessibility and adjust how notes are linked and visualized in the outline.
