As title, an addition I always wish for when playing is an in-game notepad.
A new tab in the Intel screen where the player can write down whatever they want to remember. (Where they stashed goods, locations of nice planets, plans etc.)
Sure it isn't hard to keep notes yourself, but it takes you out of the game and hurts the immersion, finding notes can take time/be a hassle, it would keep notes in a single place, it would make sure you didn't mistake notes from a different playthrough as the ones for the current playthrough.
It is only a small thing, but it always bugs me.
