The Backlink Settings plugin enhances the backlinks or 'Linked mentions' pane by allowing users to save their preferred view settings. Normally, each time a new file is opened, users need to manually adjust the sort order, context display, and whether backlink results are collapsed. With this plugin, these preferences are saved and automatically applied whenever a note is opened, streamlining the experience for those who rely heavily on backlinks to navigate and understand their note connections.
