I drag most everything I use into my Brain.
I use Virtual Thoughts for files I share with others, or that others need access to, either at work or at home. Since they don't all use PersonalBrain, I maintain a clear hierarchy for these files, and link them virtually throughout my Brain to areas where I might need to quickly access them. One way that I've worked around the lack of indexing is to create a "Virtual Thoughts" thought that connects all of these thoughts. Since I use them sparingly, I generally know what my Virtual Thoughts are, and if I don't remember exactly where I initially linked them, this creates a common thought for me to find them. One of the reasons I use them sparingly, is because this feature has seemed to be a little "buggy" to me. Generally, whenever I've had a crash, or things have slowed way down, it's been a result of clicking on a Virtual Thought. However, the benefits of PersonalBrain overall outweigh this minor glitch, and I still have the ability to have Virtual Thoughts when needed. I definitely would like to see this feature improved in future releases. For me, it's been one of the least dependable features of PersonalBrain.
