This area allows you to change the content and appearance of your dashboard by removing or adding wiki mark-up and macros. For help with macros, please see the macros documentation.
You can hit the reset button to return to the original dashboard settings and content.
NOTE: In Theme Builder 4 the dashboard markup has been moved out of the administration page and added as a layout resource. Take a look in the Manage Layouts > Resources tab, and you'll find a resource called dashboard.wiki.
