Changing filing in Preview.
I've a collection of images built up over the years under 40 or more headings and sometimes I'd like to change how Preview files stuff. Used to be, back in System 10.4 or thereabouts, on opening a page of thumbnails one could drag them into any order you wanted, and that remains true with collections made long ago.
Now everything is filed alphabetically and that's fine, but sometimes I'd really like to order a new Preview window/page by just dragging the thumbnails around. How do I go about doing that?
Thanks . . . Fortes
