We happened upon Byoby by accident while installing screen this afternoon. I quote from the project home.
It was originally designed to provide elegant enhancements to the otherwise functional, plain, practical GNU Screen, for the Ubuntu server distribution. Byobu now includes an enhanced profiles, convenient keybindings, configuration utilities, and toggle-able system status notifications for both the GNU Screen window manager and the more modern Tmux terminal multiplexer, and works on most Linux, BSD, and Mac distributions.
As with other window managers it is possible to create, destroy and move between windows.
What makes it rather unique is its use of the function keys. This might not seem like much, but it is actually very convenient to operate without obscure <CTRL> key combinations.
I’ve only been playing with it for a couple of minutes but it is a breeze to use. Notice also the time, very valuable and not usually considered in console, and some other system stats at the bottom right.
