Going to have to agree with zenrain, here. I find things in TheBrain 9, too. The visual representation of and associative thoughts often lead me to remember what I actually
have put in there, but forgotten. That's something that no other software does as well in my experience. Generally this process begins with a subject that has my attention. It isn't automatic, of course, and no system can be effective if you can't remember where you generally place things, or that you placed them at all.
Having said all that, the absolute best system I've ever found for text and retrieval is Brett Terpstra's nvAlt. It would be fantastic if TheBrain worked exactly like nvAlt in regards to its notes function, but that is the advantage of a single-focus app. I could say the same thing about vertical programs in other areas, outlines, for instance. Still, TheBrain has proven to be the best tool I've found for helping my human brain retain and recall information that has my attention, but it isn't where I do my capturing and presentation and I don't know that is has to be. We're seeing features appear on a regular basis in a steady stream of updates. The developers are responsive to their user's needs and users can roll their own organizational systems quite will with the available tools.
