MindMaster is my favorite software for creating mind maps. It has a huge collection of themes, which is perfect if you don't want to spend hours downloading a bunch of them, but still want to make beautiful mind maps. Another great feature is the ability to connect topics and assign colors to the various nodes. For example, I often color code people, locations, products, dates, tasks, etc. when making mind maps so that I can more easily distinguish between them later. This makes it a lot easier
