Essential for thinking support
One of the essential tools that tolerates and supports knowledge gathering with contextualization, providing rich visualizations of the relations. It was the tool I was looking for for long. The interface is demanding but it does it’s job once you learn it. What I appreciate is that the files can be stored offline and moved across many different platforms (tablets/computers). It is IMHO software that defines new category of thinking-supportive tools with yet unrecognized value (it comes too cheap for what it allows).
