Tilda (D-Bus)
Terminal Emulator (with D-Bus support enabled, recommended on Wayland desktops).
Tilda is a terminal emulator similar to normal terminals like 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 build-in consoles in games such as Quake or Half-live. Tilda is highly configureable through a graphical wizard.
