Editor preview up-down for mobile screen and katex support

[nmathurbkn]

Hello,

This is not an issue, this is a query. We need to use this in our react-native app. Is there any way to display the editor and its preview up and down instead of side by side?

The other thing we need is support for Katex. How we can show Katex equations in this editor.

Please let us know how to achieve this.
