Welcome back!
Actually, that sort of metadata display on the savegame listing is harder now than it even was, because now the entire save is compressed. Adding that sort of metadata display on the load game listing would add, I'm guessing, around 0.01 seconds additional load time to display that screen per save file. Possibly as much as 0.3 seconds. So with even just 10 saves, you're looking at quite a bit of extra lag with something like that, etc. It's unfortunately just not on the table -- the only way that operating systems manage that sort of thing is by building caches of that sort of data in other threads behind the scenes (Thumbs.db, etc), but that's a more sizable undertaking than we can really do at the moment.
