And old habits die hard. Many C-1 versions ago I decided to use the Linear curve setting and I've never changed it. Which means I have to build almost every image up to something I like. On the few occasions when I've experimented with the other curves like "Film Standard", I'm always a bit surprised how close they come to my own fiddling. Which means either I'm really good or C-1 is reading my mind. My biggest complaint about any of the software, including LR, is the tendency they have to add too much contrast. Hence the Linear setting.
Look forward to reading others experiences with the new catalog function.
Best,
