I have another improvement suggestion for the box set command. It is very useful by the way.

Often boxed set titles are tagged such Title XXX [Disc 1] and Title XXX [Disc 2]. The box set command places a tag of "(various)" in the Title area of the Properties dialog.

How about taking the longest matching initial substring instead (minus trailing whitespace), which in the case of the example above would auto-enter Title XXX. This would save having to either remember the long title and re-entering completely, or closing the box set dialog, opening one of the previous titles to copy text, re-opening the box command and pasting.
