Pros
Pro UTF-8 support enables character encoding
Due to UTF-8, this terminator won't mangle your favorite accented characters, and it copes well with languages where there's a mix of normal and wide glyphs (such as Greek).
Pro Unlimited scrollback
Terminator won't throw away output when it scrolls off the top of the screen, nor when it reaches any arbitrary limit.
Pro Multiple tabs
This is just like tabbed browsing, only with terminals, and means that multiple pages or documents are contained in a single window.
Pro Horizontal scrolling
Most terminal emulators wrap text when it intrudes upon the right margin. Terminator doesn't; it instead provides a horizontal scrollbar when necessary.
Pro Adds GUI features
Xiki uses some GUI concepts on top of shell. For example, commands can have nested menus and these menus are just text indented by two spaces. You can also either use the mouse or the keyboard to navigate or issue commands.
