Save User-Added Notes to Each User-Created World

I find myself making notes (simple text file) on each world that I create. These include the name of the world, the seed, coordinates for interesting places such as homes/bases, desert/jungle temples, ocean monuments, nether portals, nether fortresses/bastion remnants, etc. This comes in very useful when I revisit an old world to see all the places that I have been in it. Now, Minecraft should be perfectly capable of saving/updating such user-added notes for each world along with the other world-specific game files, and displaying it to the user on request. Consider this for s future release.
