# DESC:   turn any terminal into a dropdown terminal
# DEMO:   https://www.youtube.com/watch?v=mVw2gD9iiOg
# DEPEND: coreutils xdotool wmutils (https://github.com/wmutils/core | https://aur.archlinux.org/packages/wmutils-git/)
# CLOG:   2022-03-05   else statement to allow terminal to jump to current virtual desktop if is visible on another desktop
#         2022-02-28   added auto launch terminal if none running by https://github.com/aaccioly
#         2021-02-10   use comm to match window name and class, this avoids terminal windows with different names
