iPad UX Issues

First of all -- *thank you* for the iPad support. I wanted to bring to your attention two rather severe UX issues on iPad:

1. The iOS autocomplete bar covers the navigation bar at the bottom of Keybase, so once I start typing a message with the Apple Smart Keyboard, I can no longer navigate Keybase without quitting the app.

2. Pressing return on the Apple Smart Keyboard does not send a chat message (instead it creates a new line in the message). I have to tap the Send button to send the message.

Start by reproducing both behaviors on an iPad with an Apple Smart Keyboard: the autocomplete bar obscuring the bottom navigation and Return creating a new line instead of sending. Done means navigation remains usable while typing and pressing Return sends the chat message.
