Everything is perfect with this app, but it really would be nice to change the hotkeys (primarily the Exit button). I know this may seem small and seem insignificant to some, but as one who uses this primarily for PC games (I hate Steam) it would be so much easier if there was a way to exit Launchbox with the Escape Key instead of Alt + X. Thanks
