[Unreleased]¶

Scheduled power action never fired. The warning dialog built its message label with pady=(18, 6) — a 2-tuple is only valid on .pack(), so Tk raised bad screen distance before the widgets and countdown were created. The result was an empty "Power action" window and no Sleep/Hibernate/Shutdown at any duration, on both Windows and macOS.
Windows hibernate is now reliable. Uses shutdown /h instead of SetSuspendState(1, 1, 0), which can silently fall back to sleep on some machines. Falls back to the power API if the command is unavailable.

Documentation site built with MkDocs Material, published to GitHub Pages at https://mahanteshimath.github.io/do-not-lock-my-system/.
tests/test_power_actions.py — covers the Windows and macOS power actions and the warning-dialog render/execute flow that regressed above.

The redundant dont_lock_pc.py legacy launcher shim; use dontlockpc or python -m dontlockpc.

Scheduled power action — a "Then … after …" control to Sleep, Hibernate (Windows), or Shut down the machine once a timer elapses (minutes or a HH:MM clock time). The countdown is armed while keep-awake is running, releases keep-awake first, and shows a 30-second cancelable warning before acting. Backed by a new power_actions/power_action capability on the backend interface (Windows: Sleep/Hibernate/Shutdown · macOS: Sleep/Shutdown).

Polished the developer credit line: crisp red heart, bold underlined name, and a hover highlight on the link.

Stay awake with the lid closed (Windows) — an optional toggle that overrides the active power plan's lid-close action to Do nothing while keep-alive is running, and restores the original setting on STOP/exit. Backed by a new prevent_lid_sleep/restore_lid_sleep capability on the backend interface (lid_close_supported). Not available on macOS, where clamshell sleep requires sudo pmset.

Automated release builds — a GitHub Actions Release workflow that, on every v* tag, builds the standalone DontLockMyPC.exe (Windows) and DontLockMyPC.app (macOS) with PyInstaller, zips them, and attaches them to the published GitHub Release.

Start at login — an in-app "Start automatically at login" toggle backed by a new cross-platform autostart module (Windows Run registry key / macOS LaunchAgent).
Standalone build — a checked-in dontlockpc.spec for PyInstaller that produces a windowed DontLockMyPC.exe (Windows) or DontLockMyPC.app (macOS); pyinstaller added to the dev extras.
UI preview — docs/screenshot.svg embedded in the README.

Repositioned the app around its core use case: keeping the system awake and unlocked while long-running AI agents work. Updated README, in-app subtitle, and package metadata accordingly.
Close button (✕) now fully exits the app; the minimize button (─) hides to the system tray.

Cross-platform support for Windows and macOS via a pluggable keep-awake backend abstraction (KeepAwakeBackend).
macOS backend using the built-in caffeinate utility plus Quartz CGEvent mouse/F15 input synthesis.
Proper src/ package layout (dontlockpc) with python -m dontlockpc and a dontlockpc console entry point.
Packaging via pyproject.toml, platform-marked dependencies, and a development extras group.
System-tray wrapper that degrades gracefully where a background-thread tray is unavailable (e.g. macOS → minimize to Dock).
GitHub Actions CI (lint + import smoke on Windows and macOS), issue/PR templates, CONTRIBUTING.md, CODE_OF_CONDUCT.md, and tests.

Extracted the original single-file Windows script into a package; the Windows Win32 logic now lives in backends/windows.py.
UI now uses platform-appropriate fonts and a native title bar on macOS.
