Terminix looks like a prettier alternative to the terminator terminal. It has a lot of great color themes bundled with it and there appears to be a lot of useful features, including a side bar of terminal sessions.
To install terminix, you can run the following commands.
sudo add-apt-repository ppa:webupd8team/terminix -y sudo apt update sudo apt install terminix -y
Alternatively, if you have installed prog-exec, you can just run this one command
prog-exec "31" "e83c6311a278bdef36c1ac798c58e70d3d9b485f656cc110506db43a4734e22b"
