I have a few requests which I'm sure many other creative professionals using your product would agree with me on.
1: For us Mac Pro users, utilize/leverage both GPU's for the Develop module if possible, with every single feature accelerated.
2: Make Lightroom have an option to always make new standard or 1:1 previews with every single change you make to the picture you are working on. Some of us out here have the machines with the horsepower to do this and it would make editing soooo much more productive.
3: Make the second display just as productive as the primary display as far as previews being quickly generated and all tools and modules accelerated.
4: Many of us use Lightroom instead of Bridge to organize and cull our images. Make Lightroom able to open, preview, and fully edit any image file type that Photoshop can, such as, but not limited to; 16bit TIFF's that are greater than 4GB in size, PSD files without layers, PSB files of unlimited size without layers...
5: You've made leaps and bounds with added features in Lightroom, one of my recent favorites being the Merge to Panorama feature. Yes you can use the same thing in Photoshop but it takes a billion and a half years longer to stitch the images together, so why is Lightroom limited so badly in this area?!?! Lightroom is soooo much faster at stitching 30 or less Nikon D810 14bit RAW files that it's not even funny, but it seems to hit a ceiling after 35'ish images or so, and I'm editing on a Mac Pro with 64GB of RAM. The ability to have non-destructive editing on a panorama made of RAW images instead of 16bit TIFF's is a godsend for those of us pushing our RAW files to the limit of their dynamic range, and it would be a real sucker punch to panorama software companies like PTGui if you would enable us to make gigapixel panoramas in Lightroom.
6: And lastly, I love Lightroom Classic CC, even with my few suggestions and complaints. But my final request is that you give users more ability to control the resources that Lightroom utilizes. Things like how much RAM it can use for editing and panorama/HDR merging, what scratch disks to use on top of where the Catalog is located, how much GPU RAM, which GPU, and lastly how many CPU cores that it can use, that way we can leave one or two cores free for staying productive in other areas on our computer while Lightroom is ingesting and converting 3,000 RAW files at a time from a long wedding shoot.
Thank you for your consideration!
