You probably will not believe this but there was actually a flashlight that had this UI your talking about 8 years ago.
It sold like wild fire and was talked about in the community a lot. I was never able to get one because they had two versions and I kept receiving the 5 mode version, so I gave up. It didn’t have moonlight but was programmable for all 3 modes. Our very own SB did a review of the light.
Never could figure out why some other company didn’t copy the UI, You set it like you wanted it, what’s not to like about that.
I bet even SB forgot about this one.
Add one more mode for moonlight and all modes programmable, perfect simple UI. I still really like NarsilM though.
