I like the idea for multiple saves for one game, but I think the first idea is a bit pointless. While it would be convenient, I don't see why it's any MORE convenient then clicking one extra link.
Barring convenience, wouldn't it just make more sense? I know you're told where to access your game saves when you save, but that doesn't mean it isn't more intuitive to actually be able to load a save for a game within the game itself. Plus, it'd even make it easier to jump back to a save point while playing since you'd never need to leave the window.
