If you use st or havoc and have a tmux configuration that looks like this:

# Generic Tmux config
# use emacs keybindings
setw -g mode-keys emacs

# put the status bar on top
set -g status-style fg=green
set-option -g status-position top

# add urxvt keybindings

bind-key -n C-T new-window
bind-key -n C-pageup prev
bind-key -n C-pagedown next

# make killing of panes match emacs
bind k kill-pane

# Improve appearence
set -g default-terminal "screen-256color"
set -g pane-border-style fg=green
set -g pane-active-border-style fg=blue

# Support local files
if-shell "[ -f ~/.tmux.conf_local ]" 'source ~/.tmux.conf_local'

Then yes you do require tmux as dtach, abduco, dvtm and mtm are not up to the task

Like seriously let me do ctrl-shift-t to create a full screen tab. Show the running program names on top and let me switch between them with ctrl-pgup and ctrl-pgdn.
