Ok, I've read the first review and bought it anyway because the screen shots looked cool. It takes a little time to figure it out, but you can create unlimited items with unlimited relationships. You can mark each relationship and each item and, unlike so many mindmapping apps, you can link any item to any other item by going to "new relationship" and selecting that item from the list. At first I got scared when I thought that some of my project items disappeared, but they reappeared when I zoomed in. I think I went to "navigate to items." This prevents your project map from being too cluttered. The app is amazing. You just need to spend some time playing around with it (i.e. building new and reverse relationship, navigating to items from a control panel, saving it. etc), but it took me about 5 minutes to figure out how everything works. Best tool for planning ridiculously large projects, which is what I needed and this is the ONLY app that could do what I wanted. Five stars!!!

After installing KnowledgeBase Builder, I was initially excited and spent a number of hours working on a chapter for my finance class; however, the next morning when I tried to access that file from my SkyDrive, the data was gone. Apparently I had not pressed the save button. One would think there might be an autosave feature that would have bailed me out of that mess. No warning appeared telling me that I might lose my data. And, so, the program is a bit unforgiving. Also, I lost data while I was building my map: each time I would add a new item, it would transfer my notes from the last item along with it. But, when I deleted the notes, it removed them from the previous item, as well. Some trial-and-error allowed me to figure some of it out, but it was really frustrating. I like the idea of this program and, so I recommend it because of its price as a nice way to get an intro to the genre of mind-mapping software.
