Freeplane is an open source mind mapping software, the evolution of the well known Freemind app. I finished an export filter that can be added to Freeplane so that mind maps can be exported as an Asciidoc file. Might come handy when brainstorming and sorting ideas to draw the initial canvas of an Asciidoc based document.
The description can be found on my humble personal web site:

Although I didn't test it, it might be that this export filter works also for Freemind.
Now that I learned how to make a Github pull request, I will propose this enhancement to the Freeplane team and hope that it gets included in the next release.
