Open 2 PPTx side by side (iPad Pro-only feature)
When creating PPTx on the desktop, users constantly copy slides between PPTx to build a new deck from old content. iOS won’t allow you to open two instances of the app side-by-side, but the app itself could allow for both. With split screen, you’ve already figured out the UI for showing a PPTx on half the screen, so that wouldn’t need to change. This would be such a powerful feature!
