You can reorder server, remote desktop, and published application shortcuts.
Each time you connect to a server, Horizon Client saves a server shortcut to the Home window. You can reorder these server shortcuts by selecting a shortcut and dragging it to a new position on the Home window.
After you connect to a server, the available remote desktops and published applications on that server appear in the desktop and application selection window. Remote desktop shortcuts appear first, followed by published application shortcuts. Remote desktop shortcuts and published application shortcuts are arranged alphabetically and cannot be rearranged.
When you are in the Favorites view (you clicked the Favorites button in the upper-right corner of the desktop and application selection window), you can reorder remote desktop and published application shortcuts by selecting a shortcut and dragging it to a new position on the window.
