The multi-mouse feature is useful for clicking in two places at the same time when playing Android games. However, if for some reason you're trying to click both mouse buttons at once (e.g., by holding down something with both mouse buttons) and you move the cursor slightly, the mouse click that wasn't moving is released. By having it release what it was holding, I've also noticed that in rhythm games (e.g., Colorful Stage), on long notes, if you click one of these and hold the note, everything works fine. But again, if for some reason you move the other mouse, the note you were holding with the other mouse is released and starts clicking only while you move the mouse, which moves without holding the click (the one that caused the glitch). Basically, the goal is to be able to move the mouse freely, simulating a touchscreen. I tried all the features (Windows 10 touchscreen simulation, pen, Windows 8 touch, etc.), and none of them eliminated the problem that if I moved one mouse while holding down the other, it wouldn't release what I was holding and would start clicking on its own. It also works for painting with "both fingers" at the same time.
