Soliciting the writing of an app do solve the problem discussed in: https://www.photools.com/community/index.php?msg=95081 (https://www.photools.com/community/index.php?msg=95081)
The app will assign the selected file(s) to a category named: MyBookMarks and remember date/time.
except
If the last time such an assignment was done was more than 8 hours ago
AND there are already files assigned to this category then
warn the user: There are already nnn Files in the category MyBookMarks.
and
Ask the user to select either:
1. Assign files which have been assigned to MyBookMarks to a subcategory called MyBookMarks_stored_on_<date and time> and remove them from the category MyBookMarks. Then assign the selected files to MyBookMarks, remember date/time
2. Assign selected files to MyBookMarks (add to existing files), remember date/time.
3. (Optional) Show files in category MyBookMarks in a result window.
4. Exit (Do nothing)
Suggested name for the App: Set Category MyBookmark
Important: The category MyBookMarks will be set to sealed so that no manual assignment is possible.
If I have some time over the next week or so, then I'll see what I can come up with for you. Enjoy!
