I think there's a simple solution: Provide users the ability to reorder the Rooms Toolbar. Frankly, I'd like the subtitle room up higher. Maybe I'm in the minority; that's OK. If I can reorder the Rooms, I can exile the "Project Room" to the bottom of the toolbar (hopefully out of sight like the subtitle room currently is) and move up the subtitle room. People who love the 'Project Room' can leave it where it is.
This is a simple software change available in programs like Photoshop and Lightroom. Give users a way to put the tools they use where they want them.
