Three custum settings is useful, but how about giving us the option to add more, meaning C1, C2, C3, AND C4, C5, C6, etc. Saving to a file is a wonderful improvement but I could really make use of all these in a single day's shoot.
An upcoming example is I'm doing architectural photos of a new stadium addition on Homecoming day--so I'll be using a tripod for some and then going immediately to my people configuration and then back again. I use two and sometimes three for stills on a tripod, and then three for people to address differing light conditions. Yeah I can upload the file, but I'm going to miss something OR drop my camera fooling with it.
And sure I can use two cameras and will. But both set up identically would be a blessing.
Using an R and an R5. TSE lenses on one, fixed focals on the other.
Just because I don't pose with a camera to my eye doesn't mean I'm not a dork.
