## How to use it

The [keyboard shortcuts](https://support.apple.com/guide/mac-help/what-are-those-symbols-shown-in-menus-cpmh0011/mac) are self explanatory, but the snap areas can use some explanation if you've never used them on Windows or other window management apps.

Drag a window to the edge of the screen. When the mouse cursor reaches the edge of the screen, you'll see a footprint that Rectangle will attempt to resize and move the window to when the click is released.

| Snap Area                                              | Resulting Action                       |
|--------------------------------------------------------|----------------------------------------|
| Left or right edge                                     | Left or right half                     |
| Top                                                    | Maximize                               |
| Corners                                                | Quarter in respective corner           |
| Left or right edge, just above or below a corner       | Top or bottom half                     |
| Bottom left, center, or right third                    | Respective third                       |
| Bottom left or right third, then drag to bottom center | First or last two thirds, respectively |

In **Behavior** > **Extras**, enable **Animate windows** for smooth window resizing, or in **Snap Areas**, enable **Blur footprint** for a blurred snap preview. Both are off by default. Animated snapping keeps the selected edge or center aligned when an app limits its window size or aspect ratio. Dragging a snapped window starts restoring its previous size as the window begins moving, and a quick release lets the remaining restore animation continue. Far-right title-bar grabs can still show visible jumps. Title-bar double-click maximize/restore follows the same animation setting and timing as snapping. Window animation has been tested in known scenarios, but remains experimental because repeatedly updating the window's size and position during the transition may cause issues in some edge cases.

### Tile windows in rows or columns

In **Behavior** > **Extras**, enable **Show Extra shortcuts in menu** to include Rows and Columns in the **Tiling** submenu. Their keyboard shortcuts remain
