Cool idea, but I'm a software developer and I cannot figure out how to use this app. Something as simple as monitor brightness doesn't need so many controls, toggles, and things popping up and telling me things. It doesn't follow a single MacOS design convention.
I'm not sure why you're being downvoted but I really struggled with this application as well. Sync mode? location mode? There's help text, which I read it several times and I still have no idea what's going on.
The preferences screen is very difficult to use - it's a mix of labels and buttons with no indication that things are adjustable. You can adjust the brightness by hovering over the brightness amount and scrolling vertically. There are multiple preference panes, but they're only findable with horizontal scrolling. None of this is easily discoverable.
I use the software... but pretty much only the shortcut keys (^F2, ^F1). The other features which seem like they could be useful, would probably see a lot higher adoption if the application followed some UX best practices.
Different users have different needs. The app was extremely simple when I first launched it because I only needed an UI for ddcctl.
But as I was gathering feedback from users, I wanted to make Lunar usable in as many monitor setups as possible. And very good ideas came out of that (Sync mode being one of them) but it also cluttered the UI with a bit too many configurable values. Those are still needed by some users even though they might not seem useful for you, so I don't want to remove configurability.
I think by adding all these knobs, Lunar achieved the goal of being flexible enough to conform to most types of monitor usage. Now I just have to figure out how to simplify all this without losing flexibility.
