i still can't figure out how to do screen splits on iPad, since it was introduced in OS 11? i watched videos on it, etc, and still couldn't get it to work. the only way i got it to work is to split screens for an app that's on my dock, which itself is very limited. i ended up giving the ipad to my 5 year old as his toy and the other day it died completely. i guess i will never know.
