Version History

• •While Atrium was running, Touch ID didn't work when buying or downloading apps in the App Store.

• •The Settings window could no longer be dragged after a switch in it was flipped.

• •The app icon's background looked flat in the Dock and Finder. It now shows its gradient.

• •Windows are listed in the order you last used them, so after switching to an app from the Dock or ⌘Tab, Option+Tab takes you straight back to the window you came from instead of that app's other windows.

Fixed

• •Option+` now works when the active app has no windows, such as right after closing a menu bar app's settings, by listing the windows of the app in front.

Changed

• •Closing Settings or the welcome window returns you to the app you were using.
• •Settings uses the standard grouped layout, and ⌘W closes the window.

• •Fixed steady processor use that began once Settings had been opened and went on after the window was closed.

Added

• •Minimized windows are marked with the same diamond (◆) the Window menu uses, right before their title.

Changed

• •The selection highlight now follows what's behind the panel. Gray over a bright screen, deeper and darker over a dark one, and glowing brighter instead in dark mode.
• •The panel has rounder corners and a thinner, subtler edge highlight.

Added

• •Atrium now speaks Korean. The menu, Settings, and the welcome guide follow your macOS language.

Fixed

• •Alternating between Option+Tab and Option+` briefly flashed frosted glass while the panel changed size; the switch is seamless now.
• •The welcome guide's illustration was slightly off-center inside its panel.

• •Spotlight now finds the app by its Korean name and by what it does: 아트리움, 애트리움, 창 전환, and window switcher all match.

• •Fixed: installing by COPYING the app (instead of Finder-moving it) left it running from Gatekeeper's translocated read-only path, which blocked Sparkle updates. The app now detects this at launch, clears the quarantine flag, and relaunches itself from its real location.

• •Initial release: hold ⌥ and tap Tab to switch between windows. Every window of every app, minimized and hidden ones included, on whichever screen your cursor is.
• •Live window previews on every card, streaming in as they capture; off-screen windows (minimized, hidden, other Spaces) are pictured from the window server's retained backing store, and previews persist across relaunches.
• •⌥ scopes the switcher to the frontmost app's own windows, like the system's ⌘ but with the full panel.
• •Cycle with Tab (hold to repeat, ⇧ for backwards), move with the arrow keys, hover or click with the mouse, commit with Return or by releasing ⌥, cancel with Escape.
• •A clear Liquid Glass panel that adapts to light and dark mode, in the Domus family's visual language.
• •First-run onboarding gates on the Accessibility permission (Screen Recording optional, for previews), and Sparkle keeps the app up to date.
