I've cobbled together some similar stuff from whatever useful looking containers I come across. Because I only work on one project at a time, I don't need more organization than that. Your system is excellent for someone who works on multiple projects at (more or less) the same time. That would drive me "squirrelly bonkers." I'm not obsessive-compulsive, but I do have the tendency. Like a wolverine, once I get my teeth into something, I find it hard to let go. This is NOT necessarily a good thing.
