You can reorder server, remote desktop, and remote application shortcuts.

Each time you connect to a server, Horizon Client saves a server shortcut to the Home screen. You can reorder these server shortcuts by selecting a shortcut and dragging it to a new position on the Home screen.

After you connect to a server, the available desktops and applications on that server appear in the desktop and application selection window. Desktop shortcuts appear first, followed by application shortcuts. Desktop shortcuts and application shortcuts are arranged alphabetically and cannot be rearranged. When you are in Favorites view (you clicked the Favorites button in the upper right corner of the desktop and application selection window), you can reorder desktop and application shortcuts by selecting a shortcut and dragging it to a new position on the window.
