Hmm let's ask e.g
this user or
this one if he can check if that is possible with Slide over on e.g. iPad Air or iPad mini2.
I would use e.g. WhatsApp/iMessage (30%) next to e.g. browser (70%), e-mail.
I wish the video also kept playing with Slide Over or PIP but according to
this post that isn't the case unfortunately
. But looking at
this post the video keeps playing in PIP modus? What is it?
But looking at the
Apple iOS9 preview site PIP has the option to continue playing the video and still work in a different app (e.g. E-mail) "While using FaceTime or watching a video, press the Home button and your video screen scales down to a corner of your display.
Tap to open a second app, and your video continues to play — even while you use the other app. So keep watching your favorite TV show while you reply to the email that just came in."
It seems 'Slide Over' doesn't have this option.
