Hello, I have a Macbook Air M1 512GB. I am a teacher, I am thinking about getting iPad 10.9 64GB as my secondary device. Sometimes I need more screen space and do not have access to an external monitor. I would also use it for browsing, youtube, etc. I have a question about using iPad as a secondary monitor. I know there is an apple app that allows mirroring on the device. Can I also use it as an extended monitor where I can control what's going on? For example, I open a TV show I have saved on my mac, drag it to the ipad and control it from there, pausing it, increasing volume etc, without interacting with my mac screen at all, where I may have something else going on. Thank you!
