I currently have 12k+ images in my lightroom catalog, with another 1000+ in quick collection, etc. I feel like it's all too big. Too clunky. Slow for editing. When do I start anew? And to that end, how do I start new? I've thought of editing/hosting photos locally, then transferring them to a main catalog, but I don't really know the best way to do that. Thoughts? Cheers! Jake P.S., currently running a 2015 Macbook Pro, with the catalog and photos hosted on an external G-Drive, which I need to connect before opening lightroom.
