Drawing basic shapes and page setup

Will we ever see basic shapes like lines and arrows on the android version?

Also having a proper A4 page to be able to write something that can be printed on an actual page would be useful.

All these features are very basic in nature and were present in a OneNote version I used on a tablet PC literally ten years ago and as far as I know are present in the iOS version of OneNote. I therefore really don't believe it can be that hard to implement it.
