I know others have reviewed it as well, but I’m cautiously optimistic about this one.
TMUX provides much of the same functionality as dvtm shown earlier, however, it has a number of features that peaked my interest.
It sports the usual multiple panes, and they are adjustable. However, it allows me to block copy text which dvtm does not allow me (at least on my installation) to do. Below is a useful bar showing the active window.
For me being able to block copy is the most useful difference between the two. If someone knows how to enable that on dvtm please let me know. Other than that both window managers are excellent.
