Customize MultiMarkdown Composer
Composer version 4 has improved support for user customization in a few ways:
Customizable Themes -- customize the appearance of document windows and the syntax highlighting. See this page for more information.
Preview CSS files -- include custom CSS in the live preview and in exported HTML. In v4, this is now separate from the editor Theme for easier customization.
Expansion files -- the Pro version of MultiMarkdown Composer includes built-in text expansion. Type a shortcut and it will automatically be expanded to longer text. This can be used to automatically correct common typos, configure boilerplate documents, and much more.
You can share your own customizations here.
