* Improvement : maybe add an option in the copy/move window to choose a default action (keep, overwrite, rename) in case of read-only files, existing files or whatever that can stop the copy/move operation instead of a windows that pop-ups in the middle of the transfer
* Cosmetic : if a copy/move operation has been launched (or running), the preview in the taskbar is still showing the copy/move dialog
* Improvement : in case of failure, a dialog box would be interesting with the list of failures and actions. For instance, if there was no space left, maybe a retry would help. The list could also be exported to manually handle them later.
