Have Imatch happens to have some mechanism to see same images ( textures ) and figure out its a same thing? Then show only the one having last modification date? For example when you look through a certain project sub-folders and see lots of backup copies you might did?
In a word auto stacks showing the last modified file thumbnail ?
I recommend to start with Finding Duplicate Files (https://www.photools.com/help/imatch/search_basics.htm?dl=find-dupes) and then just sort (https://www.photools.com/help/imatch/rmh_config_sortpresets.htm?dl=hid-1) the Result Window (https://www.photools.com/help/imatch/ws_resultwnd.htm?dl=hid-1) by modification date.
Thank you Mario
