+gnome-terminal (GNOME) or Konsole (KDE), with the difference that it drops down
+from the edge of a screen when a certain configurable hotkey is pressed.  This
+is similar to the built-in consoles in some applications.  Tilda is highly
+configurable through a graphical wizard.  This version enables D-Bus support
+which is necessary for using Tilda on Wayland.")))
