When copying or moving files, an optional log window showing which files are being copied/moved and their status. Associated with that, if a file (in a long list of files being copied) can't be copied/moved for any reason, then that file should be skipped so that all subsequent files can be copied/moved. Once all files have been copied/moved, any that couldn't be copied/moved should be flagged in the log window with a "failed" status so that the user can select/click the file in the log window and decide how to proceed (i.e. retry, ignore/skip).
This would make copying/moving of large numbers of files much easier.
That's what the "Unattended operations" option is for.
Here's the relevant part of the online manual that discusses unattended operation. Darn handy feature!
