A few minor suggestions to improve on this:
- When duplicate-view is activated, Alternate-row-color is disabled temporarily (as it clutters the color-groupings, looking like separate groups)
- When dupe-view gets cleared, Alternate-row-color resumes
- A duplicate "Precision" setting, ability to set a percentage (or whatever) for % match necessary to count as duplicates, e.g. "80%" match/precision means: "ABCDE" is dupe-matched with "ABCDD"
- A dupe: search command, enabling directly appending it onto searches without mouse-input on column headers
- dupe: sub-command/parameters, e.g. dupe:size or dupe:name to dupe-check on those attributes
- ability to append multiple parameters, ordered: dupe:size,name and dupe:date,size
- Column headers that are dupe-filtered get colored (the column auto-sorting when dupe-view applies is great; column colorings would be useful when multiple columns are dupe-appended)
- Ability to adjust dupe-group colors (I don't mind what colors are used, I just can't visually discern the difference between green groupings (attached), nearly acting on some as if it was all one group)
- The "DUPE" indicator on Everything's status bar appends the attribute(s) being dupe-filtered, e.g. "DUPE:Size" or "DUPE:Name" or "DUPE:Size,Name"
- Ability to right-click "DUPE" status and remove individual dupe-filtered columns (obviously only when multiple columns have been dupe-filtered; "Clear Find Duplicates" is fine otherwise)
