# Problem: Discord keeps crashing mid-game, I don't even notice for a minute because all I see is everyone go silent for a minute
# Solution: This horrible loop that restarts it, shoves it to the side, then refocuses the app I want
# Bonus problem: Discord's priority speaker doesn't work with voice activity
# Bonus solution: This horrible xbindkeys shit that effectively inverts the push-to-talk behaviour into push-to-silence

# NOTE: This does not work properly if there's more than one window with "Discord" in the title
