Auto Dupe comparison between panes

[Invariant]

E.g., Enable Dupe comparison between panes by toggle. Selecting files in one pane selects matches in other pane. one can configure the type of match by some method such as filename, date, column, formula, substring, regex, etc. Also, optional "jump to" so that when a file is selected or highlighted, the second pane will scroll to it, ideally using the same position as the original pane so they look similar if possible. This way if the list in the view is the same one ends up being able to see the current dupe added in the secondary pane rather than it go out of buffer and not know what is happening then have to scroll the second pane to see if there are dupes. Also, probably a dupe counter. (n/M matched)

The idea is that when it is enabled and one is looking at similar sets of files, one can see it visually in the second pane.

Support for this idea.

In Total Commander I have such buttons:
- Mark files and folders that exist in both panes
- Select item with same name in opposite pane (Preserve selection)
- Select all files with same base names in inactive pane
