I'm suggesting multiple slots for quick-saves, since saving the game is noticeably intrusive.
Non-quick-saving takes us out of the moment and makes us waste several seconds every time. That's why quick-saving is a thing...
Loading isn't an issue, compared, since it's infrequent enough, and is done when we are abandoning our current activity.
So, something like 1-100 slots for quick-saves, adjustable in the "options". Quick-load brings the list of quick-saves (separate from "manual" saves).
If possible, have quick-load auto-select the latest quick-save, so that the player only has to select "load".
Needless to say, they'd be numbered (possibly "#1", "#3" and such), have dates.
