DOpus should remember if the user often copies files to specific folders. These FREQUENT COPY-TARGETS should be presented in a menu of max 10 items. So the user needs only to select a file and then click an item in this menu to copy the file to a preferred folder.
Or is there already such a feature?
Can already be done with the Favorites command and Smart Favorites, or with the Recent command, both of which can build a menu of copy targets.
Search for the word "Copy" in the manual page for either command and you'll find examples there. A link to the pages about commands is in the Opus Manual menu at the top right of this page.
