If I'm not mistaken I think QuickTime can do there where you can choose to have a window "float." That way it will always be on your screen in front of anything else you do. Anyone knows how to do this with other apps? perhaps something I need to instal to make this possible. I wanna do it with safari where I'll have that floating window play videos off the internet but at the same time I wanna be doing other stuff. Also, do you know of an extension that will allow me to have a window filled up with a YouTube video? not full screen but I can resize the window and it will continue to be just the video, not the full page. My third option if all of that is not possible I guess would be to split my screen into two screens. Although I don't think this is possible but do you guys know if there is a way where I can have my Mac treat my monitor as 2 monitors? And that I wanna can have 2 spaces running at the same time and on one of the spaces I'll have the videos playing.
