Patch #5056 by Jonathan Gordon, with rework and additions by me: Updated Viewer plugin. Replaces annoying mode-toggle key-combos with a settings menu, including a new 'Scroll by Line' option. I've also added a 'hands-free' auto-scroll feature and added lcd_setmargins to the plugin API, since we need it here.
