Brett Terpstra writes about the new integration of Marked 2 with iThoughtsX:

iThoughtsX is currently my favorite mind mapping tool on OS X. Marked 2 is, obviously, my favorite way to preview Markdown. Now they work together. You can simply drag an iThoughtsX map file to Marked, and it will start previewing an outline of your map as you work. Every time you save your map in iThoughts, you’ll see the changes in the resulting Markdown document, previewed in whatever theme you’re working with.

As you can see in the video above, the integration is seamless: every change you make in a mind map is reflected in the Markdown preview of Marked.

Both iThoughts and Marked are excellent pieces of software. I miss the ubiquitous preview capabilities of Marked on iOS, but, fortunately, iThoughts developer Craig Scott worked out a pretty sweet integration with Editorial.
