Gracefully handle multiple controllers
Currently, the default appears to use whichever controller is in first position to control the virtual mouse and other functions. But this is not always viable or preferred. The example I ran into was with the Retropie/Raspberry pi version of ScummVM on a GPI CASE 2 from Retroflag.
This case is designed to look like an old-school GameBoy system with a built-in control pad. It also can dock, like a Nintendo Switch, for big screen gaming using a Bluetooth or USB controller. In this case, the second controller would be preferred. But it was not natively functional. I had to hack a script together to make it work.

ScummVM seems to already support mapping all different buttons across multiple controllers. So, adding a way to hotswap the active may be all that is needed. A more elegant solution may be to allow the user to define a preference order, and select the first found/connected in that order. Obviously, this would require some work to be extended to game-by-game preference, if you wanted to take it that far. But an array of names in the scummvm.ini could be used to store the preference.
