Thanks for the appreciation :) I put a lot of thought into this system so it's nice to know someone at least took notice of it! Your problem of larger scale may or may not be alleviated by the details I left out for simplicity and because I assumed a typical reader may have a low scale: - In practice my "ToDo" and "Constantly needed" folders do have registers such as "health care" etc. as those are the ones where I usually have to search for things. The date sorting there is inside the registers. For "ToDo" I also color-code the registers by priority and sort them by priority. - The "Done" folders have a register for each year. For very high scale you might add registers for month. The folders are also labeled on the outside with their years. To make it easy to access things which you might have to go back to, you could add "look here!" registers which do not affect the date-sorting, i.e. like bookmarks.
