Why is the quick save count limited to 50 at most (25 is the default IIRC)? I'd rather increase that considerably, since I also quick save very frequently. Disk usage isn't really a big concern (a save on the scale of 1 MB is nothing when games these days are on the scale of 50-100 GB).

Though with less frequent auto saves and manual saves at notable times, I think there's pretty good coverage for saves even without any form of backup.
