indicate "copied" oder "moved" via status message after paste action

[jensmoeller286]

Problem

• when i mark files for copying oder moving and go elsewhere, i am regularly unsure, what i chose: copy or move?
• after pasting the files i regularly go look if they are still at the source location
• this is my attention span, but its very stressful 😅
• sadly, i often forget to look at the colored indicator for the copy/move marker-counter

Solution

• after doing the paste action, show a status message like "x items copied" or "x items moved"
• that would make it really clear to the user what was done

After you do a paste, the status line should show either Moved successfully or Copied successfully depending on whether you moved or copied files.
