For a developer, without a doubt the Settings Menu is one of the top menus most useful. It covers options like the General (general options for the site) and Design (visual options for the site) Settings, Text labels used all over the site, country and image setting and even the most impacting Advanced Settings menu where you will be able to find many variables that affect the site globally.
The Settings menu offers us:
General Settings - This sub-menu offers options like the website title, website name, default site email address, site logo, member default logo, if site is live or in development (staging mode), timezone, currency, if the site uses the universal system (metric system) or the imperial system and even to what country it is focused on, apart from many other options found in it to configure the site settings the way you like.
Design Settings - Here you are able to customize the homepage layout, add streaming widgets to your site, change colors used in many parts of the system, set which font types to use, hide multiple visual options of the site and even set which text and colors to show in various parts of your homepage, search results, pages and more.
