What is new in RainDesktop 1.2

**Mafia mode, fish and people with umbrellas.** Your desktop now has company.

- **Mafia mode** (off by default): an invincible man in a black suit fights wave after wave of gangsters in fedoras. They slide down ropes from the menu bar and leap in from the sides; he flips between windows, rolls under their bullets, fires two pistols in mid-air and sends them flying with kicks. When the screen floods, they arrive by speedboat, and he swims to a boat, throws the crew overboard and takes it. Cartoon violence, no blood.
- **People with umbrellas** float down from the sky, stroll along the top of your windows and drift down when they reach a corner.
- **Fish** swim in the flood once the water is deep enough.
- All the characters have an outline so they're easy to see on any wallpaper, and each one has its own switch in the panel.

### Install

Download `RainDesktop-1.2.zip`, open it and drag **RainDesktop.app** to **Applications**, replacing the old one. The app isn't notarized by Apple, so macOS will block it the first time: click **Done**, then go to **System Settings → Privacy & Security** and click **Open Anyway**.
