Sonny,
The screen layouts in NINA are highly customizable. They are basically drag and drop. The clean, customizable interface is a big draw. It was for me. Sometimes I find myself having to hit the layout reset button (Options>Imagining>down in the bottom right) because I got a little too carried away moving things around. There is pretty good NINA documentation for the latest stable NINA release on their website. I run the nightly beta versions, as it sounds like you do.
As far as turning the looping off, there's just a GUI toggle switch on the right side imaging page (unless you've moved it, lol). I've attached a screenshot. It took me a little while to get comfortable with NINA, but with some practice and cruising the NINA Discord server, I feel pretty good with it. Last night, I collected subs on the Cat's Eye Nebula and the Crescent Nebula. NINA handled it all while I slept. The unattended plate solving and autofocusing still seem like magic to me.
Sorry to hear about the ESD issue. Hopefully nothing sensitive got fried. I run my mount over the ethernet, so I don't really have reason to touch it except to flip on the Gemini 2 power switch on and put my telegizmo cover over it in the morning after I turn it off.? I always feel like I'm about to drop the hand controller when it's in my hands. I usually just have it hanging in a neoprene bag hanging from one of the knobs.
Clear skies,
Justin
