Blumind is a free thought mapping software that can be used to learn historical dates or various concepts from other fields. This tool is extremely easy to use and has a number of useful options. With Bluemind, the user can prepare a thought map in various variants, such as an organisation chart, a tree diagram or a logic chart. After creating the project, we will save it to many formats of raster graphics, vector graphics or in a text file, we will freely modify, review and - if necessary - print it so as not to bother the eyes in front of the monitor. In order to make it easier to use Bluemind, it is equipped with a search engine that allows you to quickly find the required fragment and, for example, replace the text or the entered term, if necessary. Bluemind has an extremely intuitive interface and allows you to prepare several thought maps in one document - between the maps you switch between them using the tabs visible at the bottom of the screen. You can also open several documents at once, which can be found in the tabs at the top of the program. If you want to customize the look of Bluemind according to your preference, you can choose one of the available themes or topics and change the font, colour and a few other elements. In addition, the program offers the possibility of creating keyboard shortcuts.
