Yes, this is intentional; I opt to use hotkeys that don't conflict. It makes flipping really fast as I don't need to focus the program. But if you would like, I could make a hotkey mode that requires window focus. Would you like that?
Oh okay! I wasn't sure if it could've also been some sort of multitasking feature and not just a bug, that's genius. But yes, a window focused hotkey mode would be awesome.
