Visible confirmation when updating PDF-asset

Request form our Content Editors:

Current situation: Hippo CMS > Assets: when I have already uploaded a PDF file, and I want to update this file with another version, I can upload via the button. When you select the file and press OK, no visual confirmation appears that the update/upload was succesfull. You can only see something has changed, when the filesize is changed. When the new file has the exact same filesize, things become unclear whether the update/upload was succesfull or not.

Desired situation: create a visual confirmation or dialogue screen which indicates that the update was succesfully executed.
