Display Groups with all files marked tool
Marking all the files in group may lead to all copies of a file being deleted. This tool helps prevent that by displaying a list of any groups which have had all the files marked for removal. Selecting a group number and clicking 'Jump to Group' or double clicking will jump to the group in the list view.
Display Mark by Location tool
Display Mark by text pattern tool

Work only on currently selected rows (Option)
When checked, Selection Assistant operations will only affect the rows selected (highlighted) in the duplicate files list.
Note, this currently excludes 'Select by Location' operations.

When checked, Selection Assistant operations will only mark groups which don't currently have any marked files.
This is useful to allow several Selection Assistant operations to be combined.
