Any Command - Turn your phone into a second screen and trackpad for PC

I built this because of a genuinely stupid problem. I have one monitor. When something is playing fullscreen on it, the machine is occupied but I still want to answer a message or check a build. Alt-tabbing kills the fullscreen. A second monitor was the sensible answer and I did not want to buy one. So Any Command can send a single PC window to the phone, and input from the phone goes to that window only. The film keeps the monitor and never loses focus. That took by far the longest to get right: Windows really does not want you delivering clicks to a background window, and Chromium apps stop rendering entirely the moment they think nobody can see them. The rest of it grew out of the same "phone is right there" idea over about two years: a proper trackpad with gestures, a keyboard, shortcut panels you build yourself, a home screen widget that can fire an automation, file transfer, clipboard sync, a gamepad, and a live view of CPU and RAM for when a render is running and you are not at the desk. There is also a Bluetooth mode where the phone pairs as an ordinary keyboard and mouse. Nothing installed on the PC at all, which turned out to be the only thing that works on locked-down work laptops and meeting room machines. It is one dev, no company, no funding, no account to create, everything runs on your own network unless you deliberately turn on internet access. For today: the first 50 people who comment get a Premium code. Reply with your phone model and I will send you one. I read every comment, and I have shipped fixes on the same day from Reddit threads before, so tell me what breaks. One thing I would genuinely like to know: if you have a spare screen sitting in your pocket all day, what would you actually put on it? I keep finding new answers to that and it keeps changing what I build next.
