The 'Composer' field to which you refer is an artifact of early versions of OrangeCD which lacked the grid. Yes, I've been using it that long. The problem with simply eliminating it is the obvious: how does one access the data stored in that field? The problem with migrating it is, how does Orange know how to break it up? You used hyphens; I used commas and sometimes semicolons. I am gradually moving the data in my DB, and I don't use the Composer field for new entries, but I'd hate to see the field (and its associated data) just... vanish... until I was done.

The ideal solution would be some kind of prompt driven migration tool (i.e. allows you to view data, specify how to migrate it, and so on). The trouble is that this is an expensive sort of thing to implement and debug for a relatively small return.
