Yes, I'm one of those peoples who regularly change their Visual Studio Code setup.
I want to cycle between different themes, try out new fonts, and switch between icons.
That's why I created 🦎 Chameleon as a weekend project.
Now, every time when I open up a new instance of Visual Studio Code, I get a new randomized look.
🦎 Chameleon looks at all the installed themes (and icons) to pick a random one, and it shuffles the font family setting to change its font.
If you also can't choose between multiple themes from the marketplace, I think 🦎 Chameleon will be for you.
