Unattended Copy is a great idea. To really add the functionality implied we need some more options....
Could we change it to assume that unattended is the default for new objects once the first unattended function is started and prior to it's completion or have it set in the settings to default to one or the other? Also let's assume the error options stay the same as well so we don't keep having the pop-up.
Once the operation is started could it automatically minimize and stay minimized until user selected or until an error is encountered?
BTW, are the error options set for each set of objects added or are they changed for all objects when another option is chosen?
Something I find I need especially when copying large files is a resume or retry until successful completion. Or at least offer the option to retry forever unless some alternative option is used like for 1 hour or 10 attempts or whatever other options might make sense. Nothing worse than coming back a few hours later to see Skip, Retry, Ignore, Abort staring back at you.
There may be some other options that I've thought of but aren't coming to mind at the moment. I'll continue posting to this topic if you like or would you prefer a new one?
I hope you feel these are desirable options. I think most of the user base will agree that they are desirable.
