Paper filing system, where frequently used documents automatically end up together—one can safely archive what hasn’t come up after a long period. Similar to that ‘touching moves it to the top of the list’ paradigm common in messaging and note-taking apps. I love learning about simple systems that are built with the right incentives to encourage what’s natural, without impeding flow. Organization can bring peace of mind and increase cognitive bandwidth, so it’s powerful to achieve this automatically.
