Add a "Post-Download Action" feature (e.g. auto shutdown after game download)
I’d like to suggest adding a new feature to Steam that allows users to choose an action after a game finishes downloading. For example, options like shutting down the computer, going into sleep mode.

This would be particularly useful for users who download large games overnight or while away from their PCs. It would help save energy, add convenience, and make Steam downloads smarter and more user-friendly.
