Guake vs Terminology

You can hit F12 (by default, though it's customizable) to open a terminal overlay, Quake-style, as a drop-down from the top of the screen.

Transparency is particularly useful for when you need to refer to the information displayed by application under Guake window.

Guake is very fast and easy to open with a customizable hotkey, meaning there's no fiddling with menus or icons.

Guake's appearance is very customizable: from the transparency to the width and height of the window. You can also choose which key to use for toggling the terminal window.

Guake is available in a lot of repositories for the most popular distros. This makes it very easy to obtain and install on almost any system.

The global shortcut key, F12, can be used to easily toggle the terminal window.

Guake supports tabs, while working with them is very easy.

You can choose byobu as shell, by adding a line to /etc/shells : " /usr/bin/byobu"
and get guake with byobu ... sweet!

Thumbnails, pictures, and videos can all be rendered in-terminal, based on the directory listing or mouse interactions. For instance, using "ls" on a picture folder will produce a list of thumbnails instead of only the filenames.

You can split windows, like in terminator.

It is very customizable in every aspect of the visual options.

Terminology is part of the Enlightenment WM packages. As such, it integrates really well with Enlightenment and other tools in the package.

You can copy text in blocks.
