Extended Nautilus replace dialog

It would be useful if Nautilus replace dialog will have some extra output and actions:
Output of sizes, dates of creation and modification of both files.
More actions: "replace if newer", "replace all if newer", "skip if newer", "skip all if newer".

...and maybe a one-way synchronization checkbox action for folder replace: "delete everything except source" - it deletes objects in destination folder that aren't exist in source folder, after copying/moving/replacing everything else.
