Thats a decent idea... Flat "knob" for grip and to be able to tell if its closed or open.We here how memory muscle is so important in every other aspect of diving...
it think it should apply to turning valves as well.
You can always use the house faucet to practice... when the water is run on your neck it's on.
We could try changing the isolator to a 1/4 turn valve... but some how I think that will cause more problems...
Like which way to turn it

I can’t think of a finer example of a task that needs muscle memory and practice.
Using the stop on a valve to indicate it’s position instead of just inherently knowing which way to turn for open or closed sounds extremely dangerous to me.

I can bet you that a serious percent, 10% for the sake of the argument, divemasters and instructors that work on cattle boats don't know how to open valves, so they fiddle with everyone's when they leave the boat and leave it half open or worse close it by accident. And those are people that open hundreds of valves weekly.
It's a skill that requires muscle memory, and muscle memory is something that needs to be practiced from time to time to retain.

If someone fiddles with my valve.
Right away I double check it.

Spend enough time working with machinery and it becomes reflexive. Finger tips just act without any perceived thinking. Mechanics, machinists, submariners, and saturation diving crew are a few examples.
Two handle hot/cold water faucets are the enemy of developing the skill.

Its call memory muscle... I instinctively know which way to turn it no matter how it sits in my hand...
If 25+ years ago when I was all thumbs and I learned only with the backwards adjustable it would be fine..
but since there is a standard for every other adjustable that I pick up it is the same, its very hard to break the habit...
(this is the only set that I have ever come across that's backwards)
If someone held a gun to your significant others head and said turn this manifold in the correct direction the first time or I shoot them, and you believed the threat to be significant I'm guessing it's slightly better than a coinflip on average for someone to be able to do it under duress. I've watched well trained shooters and and fighters make simple mistakes when asked to perform skills they've preformed well 1000s of times the first time they are under real stress. Making those mistakes less likely to happen is part of human factors that everyone wants to talk about until it's time to change how things are actually done or it challenges what they currently do.
Let's say you have 30 seconds to solve a problem, you have 1 way that solves the problem 100% correctly in 20 seconds, and one way that solves the problem correctly 70% of the time in 5 seconds, but the other 30% of the time it takes an additional 30 seconds or is never resolved correctly, which is a pretty way of solving that problem.
