I would pay good money for this for Nikon. I'm a wedding photographer and on the D750 the primary ISO button is right next to a "quality" button. Because of this, with one slip you can change from shooting raw + high quality jpeg to only basic quality jpeg. The button doesn't need to exist. Nobody ever needed to quickly change their quality settings. Most people would probably never change it. The only indication you've done this is the number of shots you can take on your current SD card will go up.

You can enable another button to be your ISO button, but it's a bit less handy to use and quite small.

Best of all, the predecessor to the D750 has the ISO and quality buttons next to each other but in a slightly different place. Fun stuff if you only upgraded one camera.

Thankfully the newer Nikons (D500, D850) have a much improved layout on the right side, iso and exposure comp are nearest the shutter button. QUAL is on top of the dial on the left, right out of the way.

Personally I think it should be removed altogether.

The one Nikon improvement I'd like is an option for bracketing and exposure compensation to be reset when you turn the camera off. That's bitten me more than once...

Nikon has an SDK program too. Though it requires you to apply first. D750 is supported.

Actually the application isn't necessary to download - just fill out the required fields spread across 7 pages and (seemingly) regardless of what you input, it takes you to the download page for the SDKs chosen (per camera and one for NEF files and one for the film scanner APIs). Haven't had a chance to look at them yet, but the most recent SDK updates are from 2017.
