Show progress status in the notification bar when operating with files in the built-in file manager

[Acorde17]

Is your feature request related to a problem? Please describe. I actually have a system running CasaOs with two 1TB hard drives. When moving a file from one drive to other a notification shows in the right corner of the screen: But if you close the current page and open it again the notification is gone and the user cant know the progress or even if the requested operation failed

Describe the solution you'd like A popup in the main menu notification bar showing the status of the file operations (copy-cut-delete...) Something like this (concept image):

Describe alternatives you've considered The only way I could see if the operations where going as they should was opening Btop and seeing the cpu usage of the linux storage system. Not the greatest solution but it worked for me.
