This is feature many have been screaming for. Depends how many scores you have. You can drag to shelves but that is only ok if you have a few. Another thing I do is sort my files by an initial letter so all my 4 part scores have a z in the file name, etc. but after a month I started converting my scores to PDF and now use forScore which has so many tags and set lists and everything else you need that I rarely use scorch now. We may get more features in another two years but scorch doesn't even recognise all the metadata fields in Sibelius.
