Compared to tmux
To some extend, pymux is a clone of tmux. This means that all the default shortcuts are the same; the commands are the same or very similar, and even a simple configuration file could be the same. (There are some small incompatibilities.) However, we definitely don't intend to create a fully compatible clone. Right now, only a subset of the command options that tmux provides are supported.
Pymux implements a few improvements over tmux:
There is a completion menu for the command line. (At the bottom of the screen.)
The command line has fish-style suggestions.
Both Emacs and Vi key bindings for the command line and copy buffer are well developed, thanks to all the effort we have put earlier in prompt_toolkit.
Search in the copy buffer is highlighted while searching.
Every pane has its own titlebar.
When several clients are attached to the same session, each client can watch a different window. When clients are watching different windows, every client uses the full terminal size.
Support for 24bit true color. (Disabled by default: not all terminals support it. Use the --truecolor option at startup or during attach in order to enable it.)
About the performance:
Tmux is written in C, which is obviously faster than Python. This is noticeable when applications generate a lot of output. Where tmux is able to give fast real-time output for, for instance find / or yes, pymux will process the output slightly slower, and in this case render the output only a few times per second to the terminal. Usually, this should not be an issue. If it is, Pypy should provide a significant speedup.
The big advantage of using Python and prompt_toolkit is that the implementation of new features becomes very easy.
