The ability to visualize the relations between concepts. The ability to perform a complex analysis of all factors and concepts affected by or affecting a notion or an idea. The ability to have an easy to use interface. The ability to have a large database. It is very easy to use. The only thing I dislike is the price. It is a bit expensive. I would recommend LinkNotions to anyone who needs a complex analysis and visualization of relations between concepts. I use it to visualize and analyze the relations between concepts in the project I am working on. It is very easy to use and it has a good database.
