Lunar 2.0 finally takes advantage of the built-in light sensor of my Macbook to bring adaptive brightness for the external displays.

Working in a room with a lot of natural light is much more enjoyable now!

Pros:

Clean design, smart algorithm, useful hotkeys

Cons:

None

@ayush_chandra Thank you! I wish it would be that easy to port it, but I would need to completely rewrite it for Windows because Lunar is written in Swift and uses low-level macOS APIs. There are a few Windows projects that allow you to control external monitors, but they're not so automated: Monitorian: https://github.com/emoacht/Monit...

Upvoted, but...

This I like about it the most:

- It's free

- It's working as described

- Has clean UI

- Smooth and logical UX

- Manual/Location/Sync Modes

What I did not like, the settings out of the box...

I set the mode to manual to test it out and I used given shortcuts to increase/decrease the brightness/contrast. It all works but changing both and having contrast really high or really low, didn't make sense.

I saw the options for setting minimum and maximum contrast/brightness and after a quick setup modifications, I liked the way it works.

It's not really a con, it's just something to think about... Maybe add a default settings out of the box that works best for most of the people?

Also, I'd really love if you can make brightness keys working, when MacBook is in clamshell (closed-display) mode. Cause currently, the keys are not working and I had to use the shortcuts provided CMD + OPT + NUMBER.

I am using my MacBook in clamshell mode all of the time, unless I hit the road. So this feature might be perfect improvement, if you can make it.

Currently I'm using an "Monitor Control" app, to have my brightness and volume controlled on external screen, but it's buggy.

Pros:

Everything it has, except...

Cons:

Some settings

Thank you for the thorough review! The default settings are what worked for me, I can't really know how other monitors are responding to these settings. That's why I added so many knobs. I'll add some analytics in the next version to check what are the most used settings so that I can adjust the defaults based on what the users are using daily. The brightness keys feature has been requested more than a few times, I'll start working on it tomorrow as I'm sure a lot will find it useful. I'd like to hear about how you would see this feature working in regards to the min/max limits and sync/location mode. I'm not sure if I should respect those limits when manually adjusting brightness/contrast through keys. In Sync mode, the best way to do this without falling back to Manual mode is to let the keys adjust the offsets instead of the brightness itself.
