The Vault Changelog plugin allows users to maintain a changelog of recently edited files within their Obsidian vault. It offers flexibility by enabling manual or automatic updates to the changelog. The plugin requires users to specify a dedicated changelog note, which can be embedded in other notes for convenience. Users can customize the number of recent files displayed and set up automatic refreshes triggered by note modifications, deletions, or renames. This functionality helps users track and manage changes across their vault more efficiently, improving organization and workflow visibility.
