Visual organizational tools are very important to me. Even if I'm in the IDE and thinking in code, when I jump tot eh browser for something I want the experience to visual and low-friction, so I don't have to push brower things onto my mental stack, which will slow me down when I want to switch back to the IDE.
I'm very good at remembering where things are, I can pick up a book I haven't touched in months and remember the page I was on, or the last sentence I read to find my place with a few seconds. On the other hand, large scale sorting and rearranging tasks are miserable drudgery so I have a lot of stacks and my bookshelves are, ah, suboptimal.
