mtm is the Micro Terminal Multiplexer, a terminal multiplexer.

It has four major features/princples: Simplicity There are three commands (change focus, split, close). There are no modes, no dozens of commands, no crazy feature list. Compatibility mtm emulates a classic ANSI text terminal. That means it should work out of the box on essentially all terminfo/termcap-based systems (even pretty old ones), without needing to install a new termcap entry. Size mtm is small. The entire project is around 1000 lines of code. Stability mtm is "finished" as it is now. You don't need to worry about it changing on you unexpectedly. The only changes that can happen at this point are: Bug fixes. Translation improvements. Accessibility improvements. Fixes to keep it working on modern OSes.
