Nightcap 0.1.1

Nightcap is a sleep timer for your computer, like the one on your TV. Pick a length (15, 30, 45, 60 or 90 minutes, or custom) and Nightcap slowly dims the screen and lowers the volume, so the show you fell asleep to trails off instead of cutting out, then puts the computer to sleep, hibernates or shuts it down. It runs from the macOS menu bar or the Windows/Linux system tray, where you can pause, add 15 minutes or cancel. Cancel the timer or wake the computer and brightness and volume go back where they were. Displays without brightness control get a dimming overlay instead. Works offline, no account needed. Written in Rust with egui; runs on Linux, Windows and macOS.
