Adjustable autosave functionality sounds good. What about a separate page for autosaves similar to how Civilization 5 did it? That would give players something like an archive for managed savepoints while the autosaves page can be used to recover from crashes, random or cheap deaths, regrets, testing, etc. The autosaves page would get clogged up (to a limit you set) but the saves would be in chronological order so sifting through them shouldn't be too bad.
