+1 for extendable width of text fields (lyrics etc) on the web interface. Or, better, a user preference width setting. I am standardizing on a landscape tablet layout that has complete song info, no scrolling, uses smaller font and text colors to highlight different parts, and because it is landscape has longer lines. I end up using Chrome inspect and removing the width constraint on the text edit div just to be productive in it as an editor.
Not for all users, I agree, hence a request for a setting of some kind.
