If I am using Facebook app (for example) and I click a YouTube video to watch, a secondary 'split' window opens, allowing me to watch the video.
However, there are times I'd like this to become the focus window, and run full screen.
I see you can drag the blue dot to increase/decrease window size, but is there a way to make the window full screen (maybe with a gesture?) and actually lose the blue dot altogether? Much like you'd do on a Windows computer using the maximize button, for example.
