I have two monitors. Sometimes I want to turn one of them off when it distracts me. But turning the monitor off causes OS to rearrange windows and sometimes even fail at that. Changing brightness programmatically also does not work reliably. So I made this.

On Linux, download the AppImage. Most likely your distro has an established way to install AppImages, like GearLevel or AppImageD. Or just doubleclick it.
Windows version is like winter: it is coming.
