Any way to enable editor max-width on mobile?

Hi folks! Not sure if this is a support request or a feature request - I'm using the Android version on a tablet and I'm wondering if there's a way to get access to the editor max width setting from desktop on mobile? The line length with the tablet in landscape mode is just a little too long to be easily readable.

The extra viewer settings plugin can do this for the viewer, but there isn't an option to do this for the editor on mobile.

I've added this to v1.5.0 of the extra Markdown editor settings plugin.

Installed, tested and looking great. Thanks so much for the speedy implementation!
