The Files preference pane allows you to configure file behavior for MultiMarkdown Composer.
Enable macOS Auto Save -- Enable the macOS automatic file save feature.
Default file extension -- Change the file extension used for new documents.
Suggest filenames for untitled documents -- When saving a new document, use the
titlemetadata (if present), or first line of the text to propose a default filename, instead of "Untitled".
*Sync macOS and MMD tags -- If
tagsmetadata exists, keep it in sync with macOS file tags. This sync is performed when a document is first opened.
File line endings -- choose which line ending type to use when saving files.
