Using either my Xbox or my PS4 controller (over bluetooth), if the controller turns off due to inactivity (no, I don't want to plug my wireless controller in to keep it from turning off), I have to restart the game to get IV to see the controller again. Can we have a hot reload feature, or a live redetection of some sort to aleviate this issue? Or is there a fix I'm unaware of?

I'll have to check this. I know Java does some controller init stuff on MC boot, and if that's the case I can't query dynamic controllers. But I'll investigate and let you know.
