Window → Save Window Layout Snapshot saves the current arrangement of all windows. You can restore it anytime from the Moom menu bar icon. Assign a keyboard shortcut for instant recall.

In Preferences → Custom, build sequences of move/resize actions triggered by a single shortcut. Chain ‘move to top-left quarter + resize to 25%’ into one keystroke.

Set the popup delay in Preferences so it doesn’t trigger accidentally when reaching for the close button. 0.3–0.5 seconds is a comfortable default.
