Let me explain why I'm trying to edit it, since this might interest others as well.
When I edit or reply on my smartphone, most of the vertical space is used up by the formatting bar and preview / help bar.
This is what I did, it's far from not perfect, but it does the job until I'll do a major theme redesign.
The one thing that I don't understand is how to "grow" the textarea all the way to the button, to maximize typing space
This is the "wide" view, with all the toolbars in place - notice the repositioned icons
This is the XS mode - notice the buttons with just the icons - no text
Finally, this is the view from my phone, in portrait view - notice all the wasted space under the textarea
