Some bugs I've encountered thus far in the Xbox BTU

Hello - I've been playing the Minecraft BTU Beta on my Xbox One and have encountered a few issues/bugs.

Bugs:
When using a keyboard and pressing the 'tab' key, the game typically crashes.

When using a keyboard to input a command or talk in chat, it brings up the Xbox keyboard.

This cannot be closed down with Enter, but you must either press 'Esc' or 'B' on the Xbox controller.

When entering a command, the game crashes when you try to repeat a command by pressing up. However, this is not always the case but it does occur the majority of times.

When using the clone command, sometimes the player will receive an error saying "Cannot clone blocks outside of the world". I've had this occur in many instances. Every time the blocks I am trying to clone are outside the render distance, most of the time when I am very close and never when on a brand new world (not ported) and nearby. Once when I tried to clone on an old ported world (while nearby), I couldn't. I exited and saved and loaded back in and tried with the exact same coordinates and it cloned.

Feedback/Issues:

When you press slash on a keyboard, please don't bring up the Xbox keyboard

Please allow us to 'Tab' coordinates for commands - it is frustrating to have to set the world spawn numerous times to find the correct coordinates and then take a picture of them and copy them out in full to use commands such as clone or fill.

Please let us button map sprint on the controller like in Console Edition.

While this is a long shot, but a suggestion, but would it be possible to let speed potions increase flying speed as well? This was very nice addition to the Xbox Edition.

Thank you for your time! I along with many others really appreciate all of the work you are putting into this. Other than these bugs and feedback, the beta is brilliant and servers are great. Thanks again!
