Great, but need new features

First, thank you for adding Apple Pencil support to 9.7 iPad Pro! Its just great now to annotate my books, documents and lessons!

The app is great, I recommend to everyone however, in order to be even better, Id love to ask you guys:
- Shortcuts keys to scroll, change tabs, documents, search, highlight, etc on physical keyboard like iPad Pro (example, option+arrow to scroll, like in chrome; cud+option+arrow to change doc tabs, etc).
- Background sync when locked or running other app! Waze, Google photos can do that, so I dont think its a system limitation for that.
- iOS enhanced language dictation/reading text. French, for example is too robot voice, different from Siri.

Thank you very much, you made an amazing app to make my iPad a capable laptop substitute!
