I also uploaded it to Macmoang, but I'm uploading it here to AI Dang as well, in order to share (under the guise of) promotional content from an AI perspective.

When using an external monitor on a MacBook, there are times when I want to adjust the brightness or disconnect the software, but existing free/paid apps didn't have the simple functions I wanted, so I made it myself.
While developing other apps (https://damoang.net/ai/4642), turning the external monitor on and off was too much trouble, so I took a detour for a while.
Since I originally intended to keep it simple, it seems like I achieved my goal in just one day.
I don't plan on putting it on the Mac App Store because it feels like there's no end if I start tinkering with it, but I might consider uploading it if it gets heavier (?)
It seems like many of those who use AI will have a Mac environment. If you are interested, please try it out and leave feedback. ^^
