The Lumberjack plugin streamlines logging thoughts and notes in Obsidian by providing quick commands and URL schemes. The 'Log' command appends a new line with a customizable prefix to your daily note, placing the cursor in edit mode for immediate input. The plugin also supports URL schemes like obsidian://log to jump directly into editing the daily note or obsidian://timber to create and edit a new draft in an inbox folder. These features are optimized for use across devices, including integration with iOS Shortcuts, enabling quick and efficient note-taking workflows.
