The symbols on the Plugins and System Settings page are called "widgets". On the System Settings page, every widget controls settings for your LoxBerry.

You can access locally stored, context-sensitive help on every page with the  symbol on the top-right corner. 

In this Wiki section you'll also find this help, and additional information and hints about the settings of the widgets.

• Every plugin and every system widget may show blue and/or red information bullets (blue = information, red = error). It informs about notifications in the plugin or system widgets.
