Terminix is a new GTK3 tiling terminal emulator. The application, which is currently in beta, allows splitting terminals both horizontally and vertically, with re-arrangeable terminals using drag and drop, and options to save and restore terminal layouts. Just like GNOME Terminal, Terminix uses the GTK VTE Widget, so it shares its features, to which it adds its own, like the terminal split functionality, a sidebar that displays terminal sessions with thumbnails (see screenshot above), support for transparency, and more.
