Make Check-in instructions and Smart Lock details a larger input box with Rich-Text

I am finding it less user friendly than Airbnb’s Smart Lock and Check-in instructions. I like that ABB has the ability to enter steps in the instructions for check-in. I would like to see a similar process on Hospitable. I also want to be able to preview what the guest will see. this is a critical step in ensuring that the guest has a smooth experience. One input box with infinite scrolling to the right is not usable.
