Having the input field and keyboard as separate things is an interesting choice.
I think it would be way better if the input field would be attached on top of the keyboard. Why? Right now when using the chat box for example, you get this huge bar in front of you that is the input field. Which you can't move. And you need to find a comfortable spot for the keyboard above or under it. Or you can move in space to get out of the input fields face a bit. It's needed since you need to have enough clearance for you to be able to hit the keyboard with your laser.
So, please connect them into one thing. You probably use both at the same time.
