I make heavy use of keywords in my catalogs to find images. Because of that, I also rely on the auto-complete keyword feature to keep them consistent. I've been using only one catalog for all of my photos, over 215,000 so far. The catalogs aren't meant to hold so many photos but when I create a new catalog it doesn't save any of my keywords or any of my other catalog-specific settings. It would be really nice to have a higher-level settings area where LrC would remember keywords, publish services, import develop settings, import presets, metadata presets, export presets, develop presets, and more. Having to recreate all these things every time I create a new catalog makes me never want to create a new catalog.
