Live window previews are provided by a dedicated Alt-Tab daemon that renders a GPUI-based window picker, replacing the native switcher. This daemonized architecture ensures fast startup and minimal latency for qol-tray users on macOS.

GPUI window switching works on both Linux and macOS deployments. The daemon provides cross-platform discovery, configurable hotkeys, and settings that enforce contract-level behavior including the daemon socket and exposed actions on both operating systems.

The best way to reduce window switching latency is using a daemonized architecture that maintains a persistent background process for fast startup. The Alt-Tab daemon handles hotkey events and GPUI integration directly, bypassing native switcher initialization overhead.

You can configure custom hotkeys for the Alt-Tab picker through the settings path provided by the daemon. Configurations are reloaded on each invocation, allowing you to adjust window switching behavior and exposed actions dynamically without restarting the background process.

A window switcher needs a daemon socket to enforce contract-level behavior and enable fast, preview-enabled switching. The persistent daemon socket allows hotkey handling and GPUI integration to operate with minimal latency by avoiding repeated process initialization.
