StickyBrain is the perfect tool to store anything and find anything, fast. Plus, you can organize your sticky notes into hierarchical folders any way you like. If you don't want to organize your notes into folders, simply hide the folder list to save some screen real estate and instead use StickyBrain like a shoebox for your notes. StickyBrain's lightning-fast searching makes it fast and easy to find whatever you're looking for. The Note Viewer is great for viewing, managing, and searching your notes. However, the Note Viewer is not required. Its use can be either optional or complementary. That is, you can open any note in its own window and then view and edit the note directly. The note is thus just a like a sticky in the physical world.
StickyBrain will let you attach an application to a note. After doing so, the note will float above other windows on your screen whenever the application is active. Suppose, for example, you attach the Safari application to a note containing a list of products you want to purchase from your favorite online store when you have some spare time. Whenever you switch to Safari, this note will float forward above other windows, including Safari windows. This convenience feature makes it easy to remember the products you need to purchase the next time you use Safari.
