Hidden Bar for Mac

New

• macOS 27 hiding is included. The arrow is the divider: ⌘-drag an icon to the left of the arrow to hide it, or to the right to keep it visible.
• The Preferences window showed a "Custom View" placeholder where the General/About tabs should be, and the placeholder overlapped the window once clicked. Only the tabs show now (#406).

Before you install on macOS 27

• Hidden Bar needs Accessibility permission to see where your icons are. Without it, the bar stays expanded.
• It relies on a private Apple framework, so a macOS update could break it. If that happens, Hidden Bar leaves the bar expanded rather than hiding the wrong things.
• Run it from /Applications. A copy anywhere else hides its own arrow.
• Hiding works per app, so an app with several icons hides or shows all of them together.
• The clock, Wi-Fi, Sound and Control Center always stay visible.
• The App Store version still can't hide on macOS 27. If you have it installed, quit and delete it before installing this one.
