The introductory video is excellent: https://www.youtube.com/watch?v=onOWVSTzzqMEverything stays in its place: icons will always stay in the same position, where you once placed them. No sorting, no re-ordering, no changes if the resolution of the screen changes. Instead, the icons are scaled accordingly to the screen resolution. You will always find your icons at the same position with a quick mouse click. Therefore the name "Places".
