“Galley view” was first used as a term in Composer’s Mosaic from MOTU, itself the successor to Professional Composer, and first released in 1992, so it is only a few years younger than Finale. So it is not a term that was invented by us: we decided to use this term at least partly because it had already been used in Mosaic.
In English the word “galley” is I think also more readily associated with the maritime world, with probably its most widely-understood meaning being that of being a ship’s kitchen. This seems also to be its earlier meaning, dating back to perhaps the 14th century. Its use in publishing came a couple of hundred years later, possibly because the trays used to hold the hot metal type were long and thin, like the old oar-driven ships that were originally called “galée” in French and “galea” in Italian.
But many words in English (and, I imagine, almost every language) have several disparate meanings, so it would be absurd to avoid using a word simply because it has multiple meanings.
And in any case I will defend our right both to assign novel names to features or user interface elements in Dorico, and to use terms of art drawn from and specific to the traditions of the craft of music engraving and publishing. We see Dorico as being a continuation of those traditions in the digital world.
