Window Management

Peekdown gives you flexible control over window layout, including native tabs, fill modes, and position presets.

Tabs

Peekdown supports native macOS tabs. Configure tab behavior in Settings > General:

• Automatic — Follows your system preference (System Settings > Desktop & Dock > Prefer tabs)
• Always — New files always open as tabs
• Never — New files always open in separate windows

Use File > Open in New Tab to explicitly open a file as a tab in the current window.

Switch between tabs with ⌘1–⌘9: ⌘1 through ⌘8 select the first eight tabs, and ⌘9 always jumps to the last tab.

⌘W closes the current tab. On the last tab with the sidebar open, it closes just the file — the window stays open and returns to the sidebar's drop zone. The red close button always closes the whole window.

Pin on Top

Keep a window floating above all other windows — useful for referencing documentation while working in another app.

Toggle from the Window menu or click the pin icon in the toolbar.

Fill Modes

Quickly snap windows to preset positions:

Position Presets

Choose a default window position in Settings > General:

• Center
• Upper-right
• Lower-right
• Upper-left
• Lower-left

New windows open at your chosen position with a slight cascade offset so they don't stack directly on top of each other.

Size Presets

Choose a default window size in Settings > General:

• Small — 500 × 400
• Medium — 600 × 500
• Large — 750 × 600

Press ⌘0 to restore the window to your preset size. When the sidebar is open, the window widens to make room for it, so the preview keeps the preset size. The sidebar itself snaps back to its default width — or refits to its content when Fit width to content is on.

Window Restoration

Enable Reopen windows on launch in Settings > General to automatically reopen your previously open files when you launch Peekdown.

Window position, size, and edit mode state are saved per file and restored automatically.
