Organizing my brushes has been driving me nuts without the ability to have categories and subfolders as we have in our Windows/Mac systems. I've been doing it alphabetically but then having to search for specifics, like watercolor or related to a class and that was taking far to long. This class is the next best thing and helps put it all into perspective, providing ideas and the means to get this organized. I've added some categories as shown in the upper left and I'll move my brushes and alphabetize them as I go. Great class!
