Would something like:

$ screen -ls
There is a screen on:
        11278.pts-23.milkyway   (Attached)
1 Socket in /home/amade/.screen.
$ TTYLIST=$(./screen -Q windows "%T,")
$ for tty in $(echo $TTYLIST | sed -e "s/,/\n/g" | sed -e "s/\/dev\///"); do
SHELLPID=$(ps ao pid,tty,ppid,args | grep $tty | grep 11278 | cut -d ' ' -f 1)
ps ao ppid,args | grep $SHELLPID | head -1 | sed -e "s/^[0-9]* //"
done
grep 11293
man man
vim
htop

be an answer?

Obviously it needs some more tweaking (grep 11293 should instead be
$SHELL window), but ultimately it lists what is running in windows.
You can then do some more things like looking where /proc/$PID/cwd
points to get shell working dir.
