Feature request: Save/Load Pane: Sort by date modified

It would be great if we could sort files by their modification dates on the save and load panes, as well as alphabetically. If it's only slightly more work, perhaps creation date and image size sorting could be options, too? I'm not sure how sophisticated a request this is, since the file panes only show names and format sorting at the moment, but I thought I would suggest it anyway.

Thanks for considering it!

Start by locating the save and load panes and the existing alphabetical and format sorting behavior. Confirm how file modification dates can be displayed or accessed there, then verify that sorting by modification date works consistently in both panes; creation-date and image-size sorting are optional ideas rather than defined requirements.
