Requested feature overview description.
when editing a post, one can click the arrows button(in the upper right corner of the edit section) to make the edit post pane mobile. It currently gets two buttons- a pin button, and an x button. The x button returns the pane to its original position. This x should be change to say "home" instead

Why would it be useful?
At first, I thought clicking the x would exit out of edit mode entirely, and lose any unsaved progress (tags, notes, etc.). It would be more intuitive for the x to instead say home, and easier for new taggers. Sometimes, there is a bug where the autocomplete suggestions will render behind the mobile pane, and the easiest way to fix this is to press x(what should be the home button) and then reclick the arrows button. This fix becomes more intuitive if the x says home instead.

What part(s) of the site page(s) are affected?
