To add some character to your screen session, add this to your ~/.screenrc :

#
# look and feel for the bottom two lines.
#
caption     always        "%{+b rk}%H%{gk} |%c %{yk}%d.%m.%Y | %72=Load: %l %{wk}"
hardstatus alwayslastline "%?%{yk}%-Lw%?%{wb}%n*%f %t%?(%u)%?%?%{yk}%+Lw%?"
#
#

This will give you hostname, date and load on one line, and the list of all screen
window names, with the current one highlighted in the second line. For deeper insights,
