diogomartino/steam-auto-shutdown ? reverse-engineered prompt

Build me a simple Windows desktop app that helps me shut my PC down automatically when my downloads are done.

I want to open the app, flip a switch to turn it on, and have it watch for download activity in the background. When the network traffic drops low enough, it should wait for an optional delay, then either shut down, sleep, hibernate, or log off, depending on what I picked. It should also let me choose which network connection to watch, set a minimum download speed so it does not stop too early, and optionally check disk activity too so it does not shut down while something is still installing or unpacking.

Please add a clean settings screen accessible from a gear icon, and make the default setup work well for most people. If you need current docs for anything, look them up online.
