How to split screen in TotalTerminal to end up with two terminals? Often when you have ssh'ed into a server, you could like a second terminal to continue right off there, without having to ssh again.

I know that iTerm2 can do it, but it feels buggy on multi screens.

TotalTerminal makes a solid impression but seems to lack that feature, unless I have overlooked it.  Is there a way to split the terminal horizontally or vertically and have two independent terminals working off the same place?
The way I achieve this is ensuring that tmux is installed on the machine I'm SSHing to.

Once you've issues tmux you can do ctrl-b % to split the screen vertically, or ctrl-b " to split it horizontally. 

This will give you two sessions within the same terminal window, and can also be persistent across logins. This may not be exactly what you want though.
