Usage: aesel
       a [directory] [TUI options]

Open the native Aesel Mac app, or activate its existing window.
The native GUI manages its own saved threads; terminal workspace flags belong to a.
Install the native Mac beta from https://aesel.app or build apple/aesel with Xcode.
AESEL_DESKTOP_APP can select a native app bundle explicitly.
