Post Description

I made a mac menu bar app that blurs your desktop when you share screen or just to focus on current active window. I share screen a lot at work and got tired of relaunching screen share every time I need to show a different window. Uses CGWindowList to track window, NSVisualEffectView for blur, and CGS API to detect when screen sharing starts (it`s an option in settings)

Posted here before https://news.ycombinator.com/item?id=47215613 but since then added auto-detect, 60fps tracking, and blur dimming.
