VYM (View Your Mind) is a tool to generate and manipulate maps which show your thoughts. Such maps can help you to improve your creativity and effectivity. You can use them for time management, to organize tasks, to get an overview over complex contexts, to sort your ideas etc.
VYM is not another drawing tool, it is a thinking tool. It is also a planning tool. Maybe some kind of database, too. The idea is to use it dynamically, just change the map when your thoughts change. The possibility to export the content e.g. to a website as seen here, was added recently. Another new export filter allows to easily create a presentation in Open Office.
