At present, when you attempt to open a file where an autosave exists, a dialog opens up asking you whether you want to open the actual file, or its autosave, along with thumbnail previews. It's very useful, and while the thumbnails make it easier to tell which file you really want, it's not always perfectly clear. In such situations, you generally have to open the autosave first (so that it's not automatically deleted) and then also open the actual save, then compare the contents. I think the dialog could be further improved by adding an option to open both files and/or adding some more info about the file - the date and time of it being saved and filesize, most obviously.
