A Moom Layout records an arrangement of window positions, but it is not a complete desktop snapshot. The distinction matters when you expect files, tabs, logins, or unsaved state to return.
What a saved layout captures
Moom’s current documentation says a Layout can save and restore positions for windows across applications, either matching particular apps or applying positions to recent windows. To create one, open and arrange the intended windows, hide or close unwanted ones, and use Save Layout.
Moom considers windows that are visible even when fully covered by other windows. Use Mission Control to inspect the set before saving. Hidden apps and minimized windows interact with layout settings, so test the chosen behavior.
What a layout cannot promise
Position data does not itself preserve document content, browser tabs, account state, unsaved edits, or a permanent identity for a window that an app closes and recreates. Moom can launch apps in some layout configurations, but its documentation describes limitations and still needs suitable live windows to match.
Validate the recovery case
Save a disposable layout, close and reopen selected apps, change a title, disconnect a display, and observe which windows return and where. Update the layout only after the display configuration stabilizes. Wallo organizes current window identity by goal; it does not save geometry, while Moom geometry does not create goal or task ownership.
