FocusFix: Separate inputs for two game windows on one Windows PC

Hi, I'm the developer of FocusFix. The setup I wanted to make easier is two people playing separate games on one PC: one on keyboard/mouse, the other on a controller. Clicking one game can leave the other visible but unable to accept input. FocusFix brings focus/input handling, cursor containment and per-workspace display/audio setup into a small C++ app. Ctrl+Shift+F12 releases the hooks and cursor lock. I've tested two DualSense controllers and DualSense + keyboard/mouse, with Crimson Desert + The Sims and The Sims + KCD. That's my test set, not a guarantee for every game. Games need windowed/borderless mode and share the same CPU, GPU and RAM. FocusFix doesn't add multiplayer, provide extra game licenses, or bypass launcher/account restrictions. I can't promise compatibility with every game or anti-cheat system. It's $4.99 once, plus applicable taxes, with no subscription. If you've tried sharing a PC this way, I'd like to hear the specific game/controller combination and what got in your way.
