I'm still saving up for fancy addons to my circa notebook, but necessity has certainly driven me to discover some interesting hacks in the mean time. Rather than dividers, I use a bunch of book darts to divide sections of my notebook, which is entirely comprised of annotation grid pages. The pages work perfectly for the Cornell note taking system. I still prefer to manage my tasks on my computer. (Which, I could talk about for hours, but I'll refrain from that digression.) But, like Patrick said, paper is generally much more accessible. So, the first page of my notebook is an "@inbox", where I dump any tasks that come to mind. When I get back to my computer, they are processed into 'the system.' The next section is a running-stram-of-conciousness-nest-of-notes. A little order is brought to the mess by date (yyyy.mm.dd) changes, and #topics in sidebars and/or across the top of the page. (book dart on the current page, so it's easy to flip to) After that, I have a page/section for each book I'm currently reading, to capture quotations. Next, several "reference pages" of lists and information I refer to regularly. (Prayers, liturgies, journaling topics). And in the very back, a list of people I'm praying for, and why.
