I see. IMHO when you die it should really load the very last save game.
But when quick loading it should never load the autosave. I also wouldn’t really want to have it load a normal manual save. If I’d like to reload from a manual save game multiple times I’d just load it once and make a quick save right away.
Beside arbitrary limitations of game slots and save slots I like this approach.
Also ideally it should be stored in file system in a directory hierarchy (e.g. one subdirectory per game slot with one description file and multiple save files in it).
This would allow easy manual copying, duplicating, backup etc.
I know, I have high demands for some very specific things
