The GUI menu system
The Proxmox GUI is a single page administration control panel. This means that no matter which feature one is managing, the browser does not open a new page or leave the existing page. Menus on the admin page change depending on which feature is being administered. For example, in the preceding screenshot, the pm4-1 node is selected, so the main menu only shows node-specific menus. If a virtual machine is selected, the menu looks like the following screenshot:

Other menu items require regular visits to ensure a healthy cluster environment, such as Summary, Syslog, Backup, Permissions, and so on:
