So, pretty jazzed so far about El Capitan; it fixed a host of tiny things that bothered me (like Mac Mail) and added some features I really like (like the new Notes app). However, I REALLY want to use Split View for working between Pages and Numbers, which it doesn't let me do. When I open one and Split View it, and go to click on the other app, it says "Not Available in Full Screen". The Split View side also say "No Apps Available". Why not? I can Split View Pages and Safari, or Numbers and say LibreOffice, but not Pages and Numbers. Anyone have an idea why? And how to fix it?
