The user interface of the Content Management system isn't all in a single place.
There are two commands in the File menu, Render Page and Render All Pages.
The Eye icon and Home icon in the left margin take you to the cursor page and the home page of the site you're editing.
Most of the prefs in the Outline Settings dialog in the File menu are used to configure the CMS.
These panels in the Settings dialog in the System menu configure the CMS: You, Insert, CMS.
There's a new readout in the right margin that shows how long the last rendering operation took, in seconds.
And sometimes when debugging a process, it helps to go into Console in the browser's debugger, if you know how to get there. The CMS code in Fargo narrates the content building process in this hidden part of the user interface.
