I actually think there's something behind the way we organize and the order/color we organize by. For some reason I move apps around until it just "feels" right. My background is the spring equinox allowing the sun to shine through Chicago. I use my iPad Air for almost anything when I'm home and I take notes in my college classes. I have Clear, which helps me organize what I need to do, I write my homework assignments there and note when I have a quiz or test. I use the iWork family of apps for school, mainly Pages. It's so easy to use and makes school that much easier. I download slide shows from my professors and open them in Keynote, I then export them to Notability when a professor decides to use presentations for their lectures.
