If you need (as I do) multitab support in mintty, you can have it with the help of ... wait for it ... SCREEN!
It was always there but I haven't got this brilliant idea to use it.
Also, do not get fulled about the title as this works in any linux like environment.

The idea is not mine. I have "borrowed" it from here with few modifications.

The script

Name it as you want, put it where you want, as long as you remember where it is and how to run it :).

#!/bin/bash

SCREEN='/usr/bin/screen'
DATE=$(date +%s)
MERGE="${SCREEN}${DATE}"

rm -f ${MERGE}
cat ~/.multitabs > ${MERGE}

cat << EOF >> ${MERGE}
caption string '%t'
screen -t "ONE"
screen -t "TWO"
screen -t "THREE"
screen -t "FOUR"
screen -t "FIVE"
select "ONE" 
EOF

screen -c ${MERGE}
rm -f ${MERGE}

The configuration file

Name it .multitabs and saved it in your user's home.
