It's a pretty common task that -- when a folder gets big-- you start creating SUBFOLDERS underneath it to help you organize. Lots of different ways people do this....
Example 1 -- <EPS Varsity Frisbee 2023>
Game 1 - vs Northwest
Game 2 - vs SAAS
Example 2 -- <Smith wedding weekend>
DONE - already edited
IN PROGRESS - keep tweaking (haven't finished individually applying adobe AI noise reduction!)
TO DO - not touched
In both these cases, it's REALLY HARD to figure out WHICH ITEMS IN THE ROOT have not yet been filed in a subfolder.
Solution: add a menu command to right-click for "Select without Subfolders" .. which only shows the images IN THE ROOT folder.
(Credit for this idea to Microsoft Digital Image Library .. a great old-and-dead photo mgmt app. :))
