Feature description

I know I can use Quick Look or press Spacebar to view the file, but that means another press of keyboard or another Esc to dismiss. The feature request is to have a Preview Pane on the right side of the window and traversing the files either with arrow keys or mouse clicks will show the preview.
Many people don't know this but Finder now has this Preview Pane (Shift + Command + P)

Why is this useful?

This feature made it easy to look at the contents before deciding if I want to Move/Copy/Delete or Sync between two folders. This is useful for PDF or JPG files. For markdown or text-related files, Actions-Compare Files can be triggered to see the diff.
