tmux vs abduco + dvtm

There is a keyboard shortcut that makes it easy to split a window and create more panes.

tmux calls the individual shell instances windows. They are displayed like tabs in the status line. These windows can be shared between different sessions, so that any given shell instance can be in any number of tmux sessions used for different purposes or by different users. This allows configurations like the following example: User A: wAB, wA1, wA2; User B: wB1, wAB, wB2

As long as you don't close your session, you may even lose your SSH connection, it'll keep your state just as it was. So you can resume where you left off (via tmux attach).

As a tiling window manager, it'll make use of all the space. As you have multiple workspaces and you can resize, etc. you can adjust to see what matters most.

Tmux is in a state of constant development. Updates are frequent and bug reports usually get an answer within days.

Open ~/.tmux.conf to get started. You can customize keybindings, the bottom status bar, color schemes, the clock screen, your time zone, and more.

Mouse support can optionally be enabled, allowing e.g. scrolling with the mouse wheel, or switching panes with mouse clicks.

Contains less code. Does not have to be backwards compatible. Two separate tools, each doing its job: session management may be used separately from tiling window/pane management.

There are the 13 shortcuts that let you accomplish the vast majority of what you'll ever need (Mod is ctrl-g by default):

Window manipulation:
Mod-c to create a window, Mod-l/h to adjust window size, Mod-j/k to change window, Mod-n to select nth window in view, Mod-enter to swap with master window, Mod-space to change layout.

Tagging:
Mod-t n to tag a window with the nth tag (1..5), Mod-T n to add/remove tag n to/from the window, Mod-v to view all windows with tag n, Mod-V to add/remove all windows with tag n to/from view, Mod-0 to view all windows.
