Yes we have tabbed documents, YAY! But' to reiterate, we still have truncated file names in the tabs and, given this is the twenty-first century there doesn't appear to me to be any real reason for that, esp when I often find myself working with iterations of a file (this years rep plot, last years, rep plot, base file, etc), the names are indistinguishable from each other. The Mac OS finder does a much better job of this (at least it gets one thing right).
