Everything it has, except...
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.
