When performing an operation on multiple files, and there is an I/O problem (for example), Nautilus pops up a dialog to inform you. Fair enough (although this does seem to be synchronous w.r.t. the I/O operation, pausing it whilst you answer). However, the messages are typically of the form:

Error copying file /media/cdr...foo.doc
Retry  |  Skip  | Cancel

or similar. This isn't very helpful if you're trying to determine which files were successfully processed and which were rejected. If the filename was there in full, or perhaps the window could be resized to accommodate the full filename (these windows tend to be fixed size, application modal, as far as I can tell) then life would be much easier. As it is, Nautilus is unusable for me when moving batches of files around between picky locations (e.g. iffy CD media, SMB/CIFS shares on Windows servers), as it's near impossible to tell using just the GUI which files were successfully processed and which need manual attention.

What would be ideal is if a 'complex' I/O operation (e.g. moving more than one file) had partial failures, a summary was displayed at the end of the operation, with complete filenames and full details of what operation(s) failed. I could then make an informed decision about what to do.

An "Ignore all further errors for this $REQUESTEDOPERATION" button might be useful, too.
