Show HN: 20 minutes of AI coding saves me 20 seconds a day

I recently moved to a new office room that's extremely bright during the day, making dark mode hard on my eyes, but at night I prefer working in dark mode. Switching macOS appearance twice a day via system settings was tedious. It felt as tedious as dialing a rotary phone instead of tapping a screen.

So, I built a tiny macOS menu bar app that toggles Light and Dark modes instantly with a single click. It only took me about 20 minutes to get the first working version up. After using it for a few weeks, I thought others might find it useful too, so I spent a few hours cleaning up the code and open-sourcing it.
