What can be displayed in the list line is fairly limited. There is a major performance different for displaying the file name and displaying info about the file. If you single click to select the savegame, the in game date is shown.SUGGESTION: Save game LOADINg, for god sake show the ingame DATE and sort the "last one at the top" ... always confused, which one to load
Have a sort option for most recent vs. alphabetical is an interesting idea. Ticket 31085.
