Xfce4-terminal has the functionality to have 1 drop-down window. This mode is inspired from consoles in computer games such as Quake which slide down from the top of the screen when a key is pressed, and slide back up when the key is pressed again.
You can start the drop-down mode by running
xfce4-terminal --drop-down. Since the application as no keybinding code, it is advised to Application Shortcuts for this.
The first time
xfce4-terminal --drop-down is passed to the application, it will create a drop-down window and show it on top of the active 1) monitor. Each other time the command is executed, the drop-down window will toggle its visibility.
When you start the drop-down window for the first time, the application opens a window on top of other windows at the top of the screen without window borders.

The drop-down preferences will be shown in the normal preferences dialog if opened from a drop-down window. You can do so by clicking the small Preferences icon in the buttom-right corner of the tab bar, right-click the notification area icon or right-click in the terminal window and choose Preferences....

When started the first time the
--drop-down option also accepts window and tab command-line parameters. You can use this to start a drop-down with multiple predefined commands. The example below will open three tabs in the drop-down window (with IRC client, music on console and process overview).
xfce4-terminal --drop-down --title "Irssi Client" -e irssi --tab -e mocp --tab --title "System Status" -e top
Another trick is to open a new tab in an existing drop-down window. You therefore need to start the with
--tab parameter, followed by
--drop-down. If no drop-down is running a new drop-down will be started.
xfce4-terminal --tab --drop-down --title "Disk Usage" -e df --hold
Note that some of the window options don't apply to the drop-down window, like --show-borders and --geometry since those are overridden by window specific preferences.
