Rectangle Pro

Rectangle Pro is a highly popular and feature-rich window management application exclusively for macOS. It is the paid, premium version of the free, open-source Rectangle app, and is designed for power users who need pixel-perfect control, advanced automation, and complex layout saving capabilities.

It builds upon the core functionality of bringing Windows-style "snap areas" and extensive keyboard shortcuts to the Mac desktop.

Key Features of Rectangle Pro

While the free version (Rectangle) covers basic snapping to halves, quarters, and maximizing, Rectangle Pro introduces significant features that elevate it to a professional productivity tool:

Advanced Customization and Layouts

• Custom Sizes & Positions: The most powerful feature, allowing users to define windows to exact pixel dimensions or percentages (e.g., $40\%$ wide, centered vertically) and assign these custom definitions to unique shortcuts.

• App Layouts: You can save a complete setup—the sizes and positions of multiple applications—as a named "Layout." This allows you to instantly restore your perfect working environment (e.g., your code editor, documentation browser, and terminal) with a single keyboard shortcut.

• Custom Shortcuts: While the free version offers shortcuts for standard positions, the Pro version allows for a much wider range of custom, user-defined shortcuts for any action or custom layout.

Enhanced Interaction

• Throw/Quick Actions: Allows users to hold down modifier keys (like $\text{Control} + \text{Command}$) and move the mouse/cursor to visually "throw" a window into a predefined snap area. This is ideal for users who prefer mouse interaction over memorizing many shortcuts.

• Window Stash: A feature to temporarily hide windows by dragging them to a screen edge, letting you unhide them by simply moving the cursor back to that edge.

• Pin Mode: Allows you to pin an application's window to the top so it's always visible, even when switching focus to another app.

Multi-Monitor and System Integration

• Advanced Multi-Display Support: Includes actions to precisely move windows between displays and arrange windows across a dual-monitor setup efficiently.

• Next/Previous Space Actions: Enables keyboard shortcuts to move the active window to an adjacent Space (virtual desktop), a capability that is often limited in free window managers.

• iCloud Sync: Syncs all your custom shortcuts, layouts, and preferences across all your Macs.
