 So, let's say that you have two speakers and two microphones, makes sense, everybody has. And you also have one application that's playing audio and one application that's recording it. So, what is the coolest way to make, as an example, a kid in life use one speaker and Firefox use another one? Well, the normal way is to just use the hamburger menu, but that's for noobs. We are cool people and we can just stick this icon and drag it to the right speaker. Same goes for Firefox. We can just drag it and make it use Q2U as an example. Same for kid in life. And we can get back to the normal speakers. Just works very nice. But we also have two microphones. Can we actually switch simple screen recorder from one microphone to the other one? Just drag it to the other microphone, which I want to do because it would ruin the audio. But we can. And I actually learned about this just today. I don't know how much it's been in plasma and it looks so good.
