v0.2.0

What's new

The first release of ZoneTab, a menu bar app for ultrawide displays that replaces AltTab and Rectangle.

• Zones on ultrawide displays. Displays 21:9 and wider get a main zone, 16:9 at full height by default, and a second zone with the rest of the width. ⌃⌥⌘↩ fills a window's zone, then the whole display; ⌃⌥⌘← and ⌃⌥⌘→ move a window between zones; hold ⇧ while dragging a window to drop it into one.
• A ⌘⇥ switcher for the zone under the mouse. It lists only the apps with a window in that zone, or on that display when it has no zones, most recently used first. Hold ⌘ and use ⇥, ⇧⇥ or the arrows, or point at an app and click it.
• Tiles survive unplugging a display, and closing and opening a laptop's lid: windows go back to their zones when the display comes back.
• Focus can follow the mouse between zones, if you turn it on in the menu bar menu or in Settings.
• ZoneTab updates itself. It looks for a new release once a day, shows what's new in it, and installs it. Check for Updates… is in the menu bar menu, and Settings › Updates turns the daily check and automatic installs on and off.

ZoneTab needs Accessibility access to move and focus windows, and asks for it when it first starts.

Downloads

ZoneTab (ZoneTab-macOS-arm64.zip) needs macOS 26 on Apple silicon. It is signed with Developer ID and notarized by Apple, and updates itself: Check for Updates… is in its menu bar menu.

Unzip it and drag ZoneTab.app into Applications before you open it: macOS runs an app opened where it was downloaded from a temporary copy, which can't update itself. Then allow it under System Settings › Privacy & Security › Accessibility. If it says it can't be updated, quit it and run xattr -dr com.apple.quarantine /Applications/ZoneTab.app.
