Something that will remind you where you left off (what you were doing, where you were going)
So... Skyrim’s quest log? A huge list of every quest you’ve encountered in the game so far, with the ability to pick one to be highlighted on the map and radar. Boot it up for the first time in a while and you can immediately see what Past You was officially working on. Pretty much every big sprawling open-world game has one of these, with a zillion text snippets to describe every possible stage of what’s happened so far in every quest, and what you need to do next.
Add a handful of generalized user-defined quests like “I am gathering (list of resources/items) so I can (make this thing/exploit this bug/do this quest a particular way)”, or maybe just an in-game notepad with some text completion assistance, and that probably covers any possible “where did I leave off”.
