Obsidian plugins with #external-app#

The Open in Marked plugin sends the current note or the whole vault to Marked 3 on macOS for a live Markdown preview outside the editor. It can open the active note directly, or keep Marked pointed at the most recently changed file in the vault, which makes it useful if you want a separate reading view while writing. The plugin works through Marked's custom URL handler and the macOS open command, so the setup stays simple but it is tied to desktop use. It also reads absolute file paths from your vault so Marked can load the right file.
