It seems that with pb3, if I select to index a file, then rename it in the database, the original file is renamed in the Finder also, I’m certain this wasn’t the behaviour before, and presents real problems for my workflow - is this a bug? or can I switch this behaviour off? I just want to work with database specific names and leave the originals as they are, as I did before.
No, this is intentional and has been requested. Just like duplicating indexed files creates new files now and settings the comments of indexed files updates the Finder/Spotlight comments immediately.
I think the more DT stays aligned with Finder, the better. I can certainly see why folks wouldn’t want changes in DT to be reflected in Finder, but this is a behavior I happen to like a lot, and I hope to see more of it in future iterations of the application.
