+
+Sometimes users just want to go directly to work and not just be greeted with
+a home screen, for these kind of situations **Mayan EDMS** has the
+:setting:`MAIN_DISABLE_HOME_VIEW` configuration option which will cause
+users to land on their ``recent document list`` as soon as they log in.
+
+Some themes such as ``default`` might be more visually appealing to some
+people without the menu icons, for this **Mayan EDMS** provides the
+:setting:`MAIN_DISABLE_ICONS` configuration option.
